Why is chemPUR the right partner for Bismuth?
We offer you much more than just products: chemPUR is your partner for demanding applications with bismuth. Our focus is on high-purity to ultra-high-purity materials that enable reliable results in research, development, and industry. Thanks to our broad portfolio, you receive bismuth in numerous forms and purity grades from a single source – from powder to sputter target.
Additionally, you benefit from our many years of experience and sound advice. Especially with complex requirements, we support you in selecting suitable materials and specifications. Our international dealer network also ensures high availability and the procurement of special products. This way, you receive a bismuth specification that is technically suitable, reliably available, and precisely tailored to your application, so you can use it directly in practice.
Which bismuth products does chemPUR offer?
Our bismuth product range includes both elemental metal and a variety of bismuth compounds. We supply bismuth in various forms such as powder, granules, pieces, ingots, rods, foils, sheets, and sputter targets. We also offer materials for special applications such as vapor deposition or thin-film technology.
Furthermore, we carry numerous bismuth-based chemical compounds. These include acetates, carbonates, halides, hydroxides, molybdates, nitrates, oxides, and sulfonates, among others. More complex or organic bismuth compounds are also available. This range covers applications in synthesis, analytics, materials science, and industrial development. Thus, you receive exactly the product form and quality your application requires.
In what forms is bismuth available?
Bismuth is available from us in a variety of forms, allowing you to respond flexibly to different requirements. Classic forms include powders in various grain sizes, granules in defined size ranges, as well as pieces and ingots for further processing applications.
For more precise applications, we also offer semi-finished products such as rods, foils, and sheets. These are available in various dimensions and purities. For special processes like thin-film technology, sputter targets and evaporation materials are also available. This diversity allows you to adapt bismuth precisely to your processes – regardless of whether you work in the laboratory or realize industrial applications.
Is high-purity bismuth available?
Yes, we offer bismuth in various purity levels, up to the ultra-high-purity range. Depending on the application, qualities from approximately 99.5% up to 99.9999% are available. This covers both standard applications and highly sensitive research and high-tech processes.
Especially in materials research, electronics, or thin-film technology, high purity is crucial for reproducible results. Our products are designed to reliably meet these requirements. Through our quality standards and broad delivery program, you can specifically select the appropriate purity. This ensures that your processes remain stable and your results meet the highest demands.
Does chemPUR offer bismuth sputter targets?
Yes, we offer bismuth sputter targets for various applications in thin-film technology. These are available in different diameters and thicknesses, for example, 3 mm or 6 mm thick, and with diameters from 25 mm to 100 mm.
Our targets are available in various purities and are suitable for processes such as magnetron sputtering or other coating methods. This supports applications in research, development, and industrial production. The combination of material quality and selection options allows you to choose the right target for your specific system and process requirements. Upon request, we can also assist you in selecting suitable specifications.
Is bismuth available as powder?
Yes, bismuth is available from us in various powder qualities. You can obtain bismuth powder in different grain sizes, for example, -325 mesh, -200 mesh, or <250 µm. Intermediate ranges such as -100/+325 mesh are also available, allowing for precise adaptation to your process requirements.
Grain size plays a central role here: finer powders offer a larger specific surface area and are particularly suitable for applications in synthesis, material development, or reactive processes where high reactivity and homogeneity are crucial. Coarser grain sizes, on the other hand, support better flow behavior and controlled dosing, which is particularly advantageous in technical applications or further processing.
In addition to grain size, you can choose from various purity levels – from standard qualities to high-purity variants over 99.99%. This makes our bismuth powder suitable for classic laboratory applications as well as demanding research and development projects. We are happy to help you find the optimal combination of grain size and purity for your application.
Is bismuth available for vapor deposition applications?
Yes, we specifically offer bismuth for vapor deposition and thin-film applications. This primarily includes evaporation materials such as specially suitable bismuth oxides in tablet form, as well as metallic bismuth in appropriate geometries. These materials are designed for processes such as thermal evaporation or other coating methods.
Additionally, sputter targets are also available, allowing you to cover different coating technologies. Due to the high purity of our materials and the selection of forms, we ensure that your coating processes run reproducibly and efficiently. This way, you receive the suitable solution for your requirements in research and industrial application.
