If you require gallium for demanding laboratory experiments, we offer purities from 99.99% up to 99.99999%, i.e. up to the 7N range. This covers both standard applications and highly sensitive analytical methods. Our product portfolio includes not only elemental gallium, but also selected gallium compounds such as oxides, nitrides, halides and other compound classes.
Whether you need small quantities for laboratory use or larger batches for industrial processes, we can respond flexibly. For custom products or individual requirements for your applications, our team is personally available to ensure you receive material that meets your specifications.
In which forms does ChemPur sell gallium?
At ChemPUR, gallium is available in several physical supply forms suitable for different applications in science and technology. If you need elemental gallium in compact form, you can choose between gallium pieces, gallium pellets and gallium ingots. The pieces are available in purities from 99.99% to 99.99999% and are offered in 10 g, 50 g and 100 g packs. For gallium as a laboratory supply, smaller pack sizes and easy-to-handle forms such as pieces, pellets or ingots are particularly relevant.
Gallium pellets with a diameter under 8 mm are also available in purities from 99.99% to 99.9999% and are particularly well suited for evaporation systems and coating processes, as they can be dosed evenly. The bar—as a gallium ingot—is available in purities of 99.99% and 99.9999% and in weights from 50 g to 250 g, and is a common form for further processing or storage of larger batches. In addition to these basic metal forms, we also offer gallium as a powder, which may be relevant for certain chemical reactions or coating processes.
We also supply gallium as an evaporation material and as a sputter target, i.e. in forms specifically designed for thin-film technologies and vacuum coating. At room temperature, the element gallium is a silver-coloured metal that becomes liquid at just over 29°C. This property also influences the choice of supply form: gallium pieces and pellets are easy to handle in the solid state, whereas liquid gallium should be filled carefully under controlled conditions and stored in a suitable original container. If you have questions about special forms or purity variations, our specialist team will be happy to assist you personally.

Where is gallium typically used?
Gallium is used in a wide range of technical and scientific applications, with electronics and semiconductor technology among the most important fields. The chemical element gallium is used primarily to produce compound semiconductors, especially gallium arsenide (GaAs) and gallium nitride (GaN). These materials form the basis for LEDs, laser diodes and high-frequency components that are indispensable in modern telecommunications and power electronics.
In recent years, gallium nitride has become established as a substrate for high-performance transistors and has driven significant innovation in the energy efficiency of power converters. In research, gallium is also used as a liquid metal, for example in metal-based liquid alloys used as thermal interface materials or in soft robotics. The low melting point of around 29.76°C makes gallium an unusually versatile material: it is still solid at room temperature, but becomes liquid already from body heat.
In medical technology and medical imaging, certain gallium compounds play a role, such as gallium citrate in nuclear medicine. Gallium is also an important raw material in photovoltaic technology, especially for CIGS solar cells. For laboratories that require gallium for demonstrations, materials studies or chemical experiments, ChemPUR offers high-purity gallium grades in various forms—from pieces and pellets through to ingots. If you have any questions about specific application scenarios, our team will be happy to assist you personally.
Which gallium products are suitable for semiconductor technology?
For applications in semiconductor technology, ChemPUR offers various gallium products and gallium compounds that can be selected depending on the process and target material. Particularly relevant are compound semiconductors such as gallium arsenide with the formula GaAs, gallium nitride GaN, gallium phosphide GaP and gallium(III) oxide Ga₂O₃. These substances are used in research and development when electronic, optoelectronic or high-performance material properties are to be investigated or specifically utilised.
Gallium arsenide is primarily of interest for applications where high electron mobility, optoelectronic properties or semiconductor-related experimental setups are the focus. Gallium nitride plays an important role in modern power semiconductors, LEDs and high-frequency applications. Gallium phosphide can be relevant for optoelectronic questions, while gallium(III) oxide is increasingly being considered in research into high-performance and high-voltage components.
In addition to these compounds, ChemPUR also supplies gallium ingots in several quality grades, including a variant in MBE Grade 8N. This quality is particularly interesting for processes that require a very pure starting material, for example in molecular beam epitaxy or in sensitive coating and deposition processes.
Gallium sputter targets are also available for thin-film processes. They are suitable when gallium needs to be applied to substrates in a controlled manner. Depending on the application, different forms, pack sizes or compounds may be appropriate. If you wish to use gallium for semiconductor technology, our specialist team will support you in selecting the right product for your process. The product groups mentioned are listed in ChemPUR’s gallium range.
What distinguishes gallium from other elements?
The chemical element gallium—with CAS number 7440-55-3—occupies a special position within the metals group of the periodic table. It belongs to Group 13 and is therefore a neighbour of aluminium, with which it is combined in certain alloys. What distinguishes gallium from most other metals is its unusually low melting point of around 29.76°C: the metal melts just above room temperature and then exists as a silver-coloured liquid metal.
At the same time, gallium has a very high boiling point of over 2,200°C, resulting in an exceptionally wide liquid temperature range. This property makes gallium valuable in certain thermal applications and as a liquid-metal heat transfer medium. Another characteristic is that gallium expands when it solidifies—similar to water—which under certain circumstances can cause damage to a device or container if the material is not stored accordingly.
Gallium is also able to wet many metals and penetrate their surfaces, which in the case of aluminium, for example, leads to a weakening of the metal structure and can cause surface damage to the substrate. For this reason, care should be taken when handling liquid gallium and contact with other metals should be avoided. Gallium is a rare by-product of aluminium and zinc production and is therefore considered a strategically important raw material. The CAS information enables unambiguous identification of the substance in databases such as those of Thermo Scientific. If you have questions about handling and storage, our specialist team will advise you directly and competently.
Which gallium compounds are available from ChemPUR?
In addition to elemental gallium, ChemPUR offers a broad spectrum of gallium compounds relevant to various fields of application in research and industry. The range includes compounds from the categories oxides, nitrides, halides, sulfides, phosphides, arsenides, antimonides, tellurides and nitrates. Gallium oxide, for example, is an important substance in semiconductor research and is used as a substrate for high-performance electronics. Gallium nitride is one of the most widely used materials in modern power electronics and optoelectronics.
Gallium arsenide and gallium phosphide are classic compound semiconductors used in photovoltaics and optoelectronics. Gallium halides such as gallium chloride or gallium fluoride are used in chemical synthesis and as catalysts. For coating processes, gallium sputter targets and gallium evaporation materials are available—product forms specifically suited to thin-film applications. The respective product data, including CAS number and specification, are documented in the item information.

How should gallium be stored after use?
Gallium has atomic number 31 and melts just above typical room temperature. Depending on the storage and working environment, it may therefore be solid or liquid. After use, gallium should be stored clean, dry and preferably in the appropriate original container to avoid contamination.
For laboratory and research applications, it is particularly important that the material does not come into contact with foreign substances, unsuitable metals or contaminated tools. Residues from previous experiments can also affect further use. Therefore, gallium should not be left open after removal and should only be handled with clean, suitable tools.
As gallium can wet or attack certain metals, contact with unsuitable metal surfaces should be avoided. For storage, tightly sealed, clean and chemically suitable containers are therefore preferred. If gallium has been used for sensitive experiments, coating processes or analytical purposes, it should only be reused if the material quality still matches the application.
At ChemPUR, you can obtain gallium in various variants, including as pieces, pellets, ingots, foils and sputter targets, as well as as a low-melting gallium-indium-tin alloy. Which form is suitable for your application depends on handling, dosing, storage and process conditions. Especially for gallium as a laboratory supply, clean storage is important so that the material remains suitable for further experiments or demonstrations.
