Why is ChemPUR the right partner for buying tin?
We offer you far more than the mere distribution of tin – we see ourselves as a reliable partner for your projects in research, development and industry. Our range includes tin in a wide variety of forms and purities, up to ultra-high-purity grades of up to 99.9999%. This provides the basis for reproducible and precise results in demanding applications. At the same time, you benefit from our international distributor network, which ensures worldwide availability.
Especially for complex requirements, we support you with technical advice and practical know-how – for example when selecting suitable purities, particle sizes or compounds. We also realise customised special products when standard products are not sufficient. Our ISO 9001 quality management system and many years of experience in fine chemicals underscore our commitment to providing you with a reliable and predictable supply.
Which tin halides are available?
In our ChemPUR portfolio you will find a wide selection of tin halides used in a variety of ways in research and industry. These include, in particular, tin(II) and tin(IV) compounds such as chlorides, bromides and fluorides. Examples include tin(II) chloride (anhydrous or as dihydrate), tin(IV) chloride, as well as tin(II) bromide or tin(II) fluoride. These compounds are available in different purities and are suitable for applications in synthesis, catalysis or analytics.
The different oxidation states of tin – primarily Sn(II) and Sn(IV) – enable targeted adaptation to specific chemical processes. We support you in selecting the right compound, tailored to your application and process requirements. Thanks to our international network, we can also supply special or less common halides, ensuring a high level of security of supply.
Are ultra-high-purity tin granules available?
Yes, we offer tin granules in various purity grades – up to ultra-high-purity qualities of 99.9999%. These granules are available in different grain sizes and are particularly suitable for applications where defined material properties and high homogeneity are required. Ultra-high-purity tin granules are used, for example, in materials research, alloy development, or as a starting material for further processing steps. Their defined form makes them easy to dose and process, making them a practical alternative to powder or ingots. We support you in selecting the appropriate purity and specification – especially when your application places special requirements on trace elements or impurities. This ensures you receive exactly the material that best fits your project.
Which tin compounds does ChemPUR offer?
Our range includes a wide variety of inorganic and organometallic tin compounds for a broad spectrum of applications. In the inorganic segment, we offer, among other things, oxides, halides, sulfates, selenides and tellurides. These include, for example, tin(II) oxide, tin(IV) oxide, or tin chlorides in various purities.
We also supply organometallic tin compounds such as acetates, alkoxides and organic derivatives based on butyl or phenyl groups. These compounds are used, among other things, in catalysis, materials development or specialised synthesis processes. Thanks to our broad portfolio, we can cover both standard applications and highly specialised requirements. If you require a specific compound that is not included in the standard range, we will be happy to review the possibility of individual sourcing or a custom product.
What is tin used for in research?
Tin plays an important role in research because it combines versatile physical and chemical properties. It is used, among other things, in materials science, electronics research and chemistry. Typical applications include the development of solders and alloys, studies on corrosion protection, and the production of functional materials.
Tin oxides are particularly relevant, as they are used in sensors, transparent conductive coatings, or as components of modern energy systems. Tin is also frequently used in thin-film technology and in the development of new coatings. Thanks to its various oxidation states and its ability to form stable compounds, tin is also ideally suited for catalytic processes and analytical applications. This versatility makes it an indispensable material in numerous fields of research.
Is tin available as nanopowder?
Yes, we also offer tin as nanopowder – for example with particle sizes below 100 nm. These nanoscale materials are characterised by a large specific surface area and special physical properties, making them particularly interesting for modern research applications. Tin nanopowder is used, among other things, in materials development, energy storage solutions or catalysis. The reduced particle size enables new reaction pathways and improved material properties compared with conventional forms. At ChemPUR, we supply nanopowders to defined specifications so that you can achieve reproducible results. At the same time, we support you in selecting suitable parameters such as particle size, purity or surface characteristics – tailored to your specific application.
Is tin suitable for thin-film technology?
Tin is ideally suited for thin-film applications and is frequently used in this field. Especially in the form of sputtering targets or evaporation materials, it enables the production of uniform, functional layers on a wide range of substrates. Its good electrical and thermal properties, as well as its ability to form stable oxides, make tin an important material in coating technology. Tin oxides are used in particular in transparent conductive layers, sensors or electronic components. We offer tin in suitable forms for thin-film processes – including sputtering targets in various purities as well as materials for evaporation processes. We also advise you on selecting the right specification to achieve optimum results in your process.
