What are pure metals and what are they used for?
Pure metals are metals with a very high degree of purity, where undesirable foreign substances are reduced to a minimum. In research and laboratory environments, this high purity is crucial, as even the slightest impurities can influence chemical reactions, measurement results, or material properties. Pure metals are therefore used wherever precise and reproducible results are required. Typical applications are found in materials research, thin-film technology, analytics, and the development of new materials. Pure metals also play an important role in chemical synthesis, for example as starting materials or catalysts. In physical applications, they are used, for instance, for electrical or thermal investigations.
ChemPUR provides pure metals in numerous forms – including powders, wires, foils, or semi-finished products. This variety makes it possible to match materials exactly to the respective application. Through the combination of high purity and the appropriate form, research institutions and development departments can optimize their processes and achieve reliable results. Furthermore, we actively support you in selecting the suitable material. Whether it is purity, form, or a specific application – our experts provide individual and practical advice to find the optimal solution for your requirements. In this way, we ensure that you not only receive the right product but also the best possible basis for your research and development work.
What purities does ChemPUR offer for metals?
ChemPUR offers metals in a wide spectrum of purity levels – from high-purity to ultra-high-purity. Depending on the application, materials with purities up to the range of 6N or 7N (99.9999% and higher) are available. These purity grades are particularly required for demanding applications in research and development where even minimal impurities must be excluded.
The selection of the appropriate purity depends heavily on the field of application. While lower purities may be sufficient for certain technical applications, analytical procedures or high-tech processes require the highest material quality. ChemPUR supports you in the selection through expert advice and many years of experience in the field of high-purity materials. A central advantage lies in constant quality assurance. Certified quality management according to ISO 9001 ensures that the delivered materials meet the specified requirements. This gives laboratories and development departments the necessary security for their processes.
In what forms does ChemPUR supply pure elements?
Pure elements are offered at ChemPUR in an exceptionally wide variety of forms. These include nanopowders, powders, granules, pellets, pieces, wires, rods, tubes, foils, sheets, and sputtering targets. This diversity is a decisive advantage, as different applications require specific material forms.
In materials research, for example, powders or nanopowders are frequently used, while thin-film technology requires sputtering targets or evaporation materials. For mechanical or structural applications, on the other hand, rods, wires, or sheets are used. Additionally, at ChemPUR, we enable you to realize special shapes and individual geometries. This allows us to adapt the materials exactly to your specific experimental requirements or production processes. This flexibility makes it possible to reliably serve both standard applications and highly specialized projects.
What are typical applications for alloys?
Alloys are used to specifically combine or improve material properties. By combining several metals, properties such as mechanical strength, electrical conductivity, or temperature resistance can be optimized. In research and development, alloys are therefore an important component in the development of new materials and technologies. Typical applications are found in sensor technology, measurement technology, and high-temperature processes. Alloys are also used in electronics or for functional materials. In many cases, they enable properties that could not be achieved with pure metals alone.
ChemPUR offers both standard alloys and customized solutions. Especially for specialized applications, it is crucial that the composition is exactly matched to the requirements. Through the combination of material expertise and manufacturing capabilities, individual solutions can be developed that are optimally tailored to the respective purpose.
What are sputtering targets and what are they used for?
Sputtering targets are solid materials used in thin-film technology to apply thin layers of material onto substrates. This process, known as sputtering, is one of the most important technologies in modern materials science and is used, for example, in semiconductor technology, optics, or coating technology.
In this process, the target is bombarded with ions in a vacuum chamber, which releases atoms from the material and transfers them to a surface. The quality of the target has a direct influence on the properties of the generated layer. Therefore, high purity and precise material composition are crucial. ChemPUR offers sputtering targets made of metallic and non-metallic materials as well as in various purity levels. Furthermore, custom adjustments are also possible, for example regarding geometry or composition. This allows you to optimally coordinate your processes and realize high-quality coatings.
Does ChemPUR supply materials for thin-film technology?
Yes, ChemPUR offers a comprehensive portfolio of materials for thin-film technology. These include, in particular, evaporation materials and sputtering targets in various forms, purities, and material classes. These products are specifically used for applications in physical vapor deposition (PVD).
The materials are available both as pure metals and as alloys, oxides, or other compounds. This allows for a wide variety of layer properties to be realized, for example in terms of electrical conductivity, optical properties, or chemical resistance. Additionally, at ChemPUR, we offer further services such as the production of targets using casting or powder metallurgical processes, as well as bonding and the manufacture of backing plates. This combination of product and technical implementation enables precise integration into existing processes and supports you in the development of new applications.
Can ChemPUR implement special metal requirements?
ChemPUR specializes in implementing complex and individual requirements. In addition to the extensive standard portfolio, the company offers customized solutions that are precisely tailored to the needs of research institutions and development departments.
These include, among others, custom-made semi-finished products, special material forms, or individually developed alloys. ChemPUR can also provide solutions for unusual purity requirements or specific material combinations. Implementation takes place in close coordination with you to ensure that all technical requirements are met. A major advantage lies in the combination of experience, technical competence, and flexibility. These factors allow us to reliably support even demanding projects – from the selection of suitable materials to the finished solution.
