Why is ChemPur the right partner for cerium?
As a provider of fine chemicals and high-purity materials, we understand the requirements of modern research and development in detail. We supply cerium and cerium compounds in various degrees of purity up to ultra-high purity grades and support you in selecting the right product for your application. You benefit from our wide range of metal forms, chemical compounds, and specialty materials for demanding processes. These include, among others, applications in catalysis research, where defined oxidation states and high purities are crucial, as well as thin-film and coating processes (e.g., PVD or sputtering processes), where material homogeneity and dimensional accuracy play a central role.
Precisely tuned cerium compounds are also required in material development and materials research, such as in the production of functional ceramics or oxide systems, as well as in preparative chemistry and synthesis development. Furthermore, we support applications in analytics where reproducible purities and defined compositions are essential. Especially in such demanding processes, the following applies: the more specific the requirements for material, form, and purity, the more important it is to have a reliable partner who can deliver these exactly.
Our international dealer network enables a reliable supply of cerium products worldwide. At the same time, we place great value on personal consultation and short decision-making paths – an advantage, especially for complex requirements or custom solutions. Individual forms or special delivery conditions, such as under argon, can also be realized upon request. As an ISO 9001 certified company, we stand for tested quality, delivery reliability, and a balanced price-performance ratio. Thus, we accompany you from the first inquiry to the secure delivery.
What is Cerium?
Cerium is a chemical element from the lanthanide group and belongs to the so-called rare earths. It is characterized by high reactivity and versatile chemical properties, which make it interesting for numerous applications in research and industry. As a metal, cerium occurs in different forms and can be supplemented by various chemical compounds. Particularly relevant is its ability to switch between different oxidation states, which makes it valuable for catalytic processes and material developments.
In practice, cerium is used both as a pure metal and in the form of compounds. These include, among others, oxides, nitrates, sulfates, or halides. Depending on the application, purity, physical form, and chemical composition differ significantly. For precise applications in the laboratory and industry, the selection of the appropriate cerium product is therefore crucial – both in terms of purity and the desired material form.
Even small deviations in purity or structure can significantly influence reaction behavior, material properties, or process stability. Likewise, the correct form – whether powder, wire, foil, or target – plays a central role in further processing and integration into existing processes. This is exactly where we support you with our technical know-how: we at ChemPUR help you select the right cerium product for your application – tailored to your requirements for purity, form, area of use, and process conditions. Together, we ensure that you achieve reliable and reproducible results.
What is cerium used for?
Cerium is used in numerous areas of research and industrial development. Due to its chemical properties, it is particularly frequently used in materials science, catalysis research, and surface technology. A central field of application is catalytic processes, in which cerium compounds play an important role due to their redox capability. Additionally, cerium is used in the development of functional materials, for example in coating technology or thin-film processes.
In laboratory applications, cerium often serves as a starting material for syntheses or as a component of complex chemical systems. It is also regularly used in analytics and in the development of new materials. The wide variety of available forms and compounds allows for targeted adaptation to different requirements – from basic research to specialized industrial applications.
In what forms is cerium available?
Cerium is available in a variety of physical forms to meet different requirements in research and industry. These include metallic forms such as pieces, foils, wires, and rods, which are used particularly in material processing and technical applications. Furthermore, we also offer cerium as powder and nanopowder, which are particularly suitable for chemical reactions, syntheses, and highly specialized applications. Sputtering targets are also available for thin-film and coating processes.
In addition to the metallic forms, cerium is also available as a component of numerous chemical compounds. These differ in structure, reactivity, and purity depending on the field of application. Through this variety at ChemPUR, you can tailor cerium exactly to your application – from simple laboratory experiments to complex development projects with specific material requirements.
Which cerium compounds does ChemPUR offer?
Our range includes a wide selection of inorganic cerium compounds for various applications. These include, among others, nitrates, sulfates, oxides, hydroxides, carbonates, as well as halides such as chlorides or fluorides. The portfolio is supplemented by other compounds such as acetates, oxalates, and phosphates. This variety makes it possible to provide the appropriate chemical form for almost every application – be it for synthesis, analytics, or material development.
The compounds offered are available in various purity grades and can be delivered as powder, crystalline substance, or in other suitable forms as required. Through our broad delivery program and our international network, we are able to provide even special or less common cerium compounds. This way, you receive all relevant materials from a single source – tailored to your individual requirements.
What purities are possible for cerium?
The purity of cerium is a decisive factor for many applications in research and industry. We offer cerium and cerium compounds in various purity levels, typically ranging from about 99% to 99.999% (REO). This range allows for precise adaptation to different requirements. While lower purities are often sufficient for standard applications, sensitive processes such as catalysis, thin-film technology, or materials research require particularly high purity grades.
Our products are specified accordingly and offer high reproducibility and reliability. Depending on the product category and application, different purity levels are available. We support you in selecting the appropriate purity for your project – taking into account costs, availability, and technical requirements. Thus, at ChemPUR, we ensure that you receive exactly the quality that your application requires.
Is cerium oxide available as a nanopowder?
Yes, cerium oxide is also available as a nanopowder and represents an important product form for specialized applications. Cerium(IV) oxide nanopowder is characterized by a particularly high specific surface area and defined particle sizes in the nanometer range. These properties make it ideal for applications in materials research, catalysis, or functional coatings. Due to the fine structure, reaction processes can proceed more efficiently, which is particularly advantageous in catalytic or surface-based applications.
The available nanopowders differ in terms of particle size and specific surface area and can thus be specifically adapted to the respective application. In addition to classic powders, we also offer different purity levels, so that both standard applications and highly specialized research projects can be covered. Thus, cerium oxide is also reliably available in the nano range at ChemPUR.
