Why is ChemPUR the right point of contact for cobalt?
Cobalt is used in research and industry in a wide variety of forms—for example, as powder for materials-science investigations, as nanopowder for finely tuned surface properties, or as a sputter target for thin-film applications. Accordingly, it is important to select not only the element itself, but also the appropriate purity, particle size and geometry in a targeted manner.
As a specialised supplier of fine chemicals and research supplies, ChemPUR has an extensive and differentiated cobalt range. We offer cobalt in elemental form as well as in compounds, in various purity grades, particle sizes and geometries—from nanopowder to sputter targets. This means you receive not only standard products, but also specifically characterised materials with defined specifications.
Flexible order quantities allow for both small laboratory amounts and larger research batches. Our specialist team supports you in selecting the right product form or purity with application-focused advice. We will be pleased to help you find the optimal solution for your application.
Is cobalt delivered worldwide?
ChemPUR supplies cobalt and cobalt compounds to customers worldwide. Research institutions, universities and industrial companies from various countries rely on our dependable supply chain and the consistent quality of our products. All relevant national and international regulations for shipping chemicals and dangerous goods are complied with. Depending on the destination country, product category and order quantity, delivery is made in suitable, safety-compliant packaging.
This means that, as an international customer, you can rely on the same service standard as our customers in German-speaking countries. In addition, we provide advice on export-related matters—for example, regarding customs documentation or safety data sheets. For your application, timely coordination is important for larger or time-critical orders. Contact us for an individual quotation—we will be pleased to support you throughout the entire ordering process.
In which purities is cobalt available?
At ChemPUR, cobalt is available across a broad purity spectrum that meets the requirements of a wide range of application areas. Our range includes grades from 99.5% up to 99.99%, covering both technical and high-purity research applications. Particularly fine powders with a grain size of 2–4 micrometres are available at 99.5% purity, while grades such as 99.95% or 99.99% are available for more demanding processes.
The range also includes cobalt nanopowder with an average particle diameter of 28 nm at a purity of 99.8%. Depending on requirements for trace-element freedom—for example with regard to nickel content—specially characterised batches are available. In practice, this means you can select the purity level that is right for your application directly, without having to compromise. We will be pleased to advise you on selecting the optimal purity for your specific area of use.
What applications is cobalt used for?
Cobalt is used in research and industry wherever magnetic, catalytic or high-temperature-resistant properties are required. As a ferromagnetic metal, it is particularly suitable for materials-science applications, for example for permanent magnets, magnetic layers and storage media.
Cobalt also plays an important role in coating technology. Sputter targets and evaporation materials are used to produce thin functional layers with defined magnetic or electrical properties. In synthetic chemistry and catalysis, cobalt is used as an active material or as a component of suitable compounds.
Further fields of application include high-temperature and hard-metal alloys, nanotechnology and energy storage research. There, cobalt is relevant, among other things, as a component of cathode materials for lithium-ion batteries. Which product form is best suited depends strongly on the respective application—for example, whether powders, nanopowders, sputter targets, evaporation materials or cobalt compounds are required. We will be pleased to support you in selecting the right cobalt product.
Which cobalt compounds are available?
In addition to elemental cobalt, our range includes various cobalt compounds that can be selected depending on chemical function and area of application. For synthesis processes and the production of functional materials, for example, cobalt acetates, cobalt nitrates and cobalt sulfates are suitable. These classes of compounds are often used where cobalt is required in soluble or readily processable form.
If oxide materials are required, cobalt oxides are available. They are particularly relevant for applications in catalysis, battery research and ceramics technology. For specialised materials-science and vacuum-technology processes, the range also includes cobalt borides as well as cobalt evaporation materials.
For demanding precursor applications, for example in chemical vapour deposition or coordination chemistry, cobalt pentanedionates are available. Cobalt halides expand the selection for applications where reactive or salt-like cobalt compounds are required. In addition to the compound class, the respective purity and specification are decisive for selection. Please contact us—we will be pleased to support you in finding the right cobalt compound for your research or development process.
How is the quality of cobalt ensured?
Quality assurance plays an important role at ChemPUR. All cobalt products are described according to fixed specifications, for example with regard to purity, particle size and chemical composition.
For cobalt powders, purity grades and grain sizes, among other parameters, are documented. For cobalt nanopowders, you will also find information on particle size, specific surface area (BET) and morphology. Important trace elements, for example nickel content, are also stated for relevant products. This provides you with traceable quality information for each item, making it easier to select the right material. On request, we will be pleased to provide certificates of analysis or further product documentation.
Which cobalt forms does ChemPUR offer?
At ChemPUR, cobalt is available in various physical forms so that the material can be optimally matched to the respective processing process. For powder-based applications, cobalt nanopowder with an average particle diameter of 28 nm as well as micropowder in various sieve fractions are available, including -50 mesh, -200 mesh and -400 mesh.
For applications where a coarser or more easily dosed material form is required, ChemPUR offers electrolytic cobalt flakes, granules in the 1–3 mm fraction, and cylindrical pellets. These forms are particularly suitable for processes where flow behaviour, surface area or dosing properties play a role.
For technical and materials-science applications, the range also includes cobalt foils, wires, rods and sputter targets. These product forms are primarily used when defined geometries, mechanical stability or thin-film requirements are the focus. Which form is best suited depends on your process—for example on particle size, geometry, surface and further processing. We will be pleased to support you in selecting the appropriate cobalt product form.
