Why is ChemPUR the right partner for boron?
Consistent quality is the prerequisite for reliable use of boron in research and industry—and this is precisely what ChemPUR ensures through its ISO 9001:2015 certification. The range extends from amorphous boron powder in technical grade to crystalline boron in dopant quality with 99.995% purity, complemented by numerous boron compounds. Materials not included in the standard program can also be procured through our worldwide distributor network. For project-specific specifications—such as rods in non-standard dimensions or special grades—we are pleased to clarify available options.
As an owner-managed family business, we operate without call centers: inquiries reach experienced specialists directly, who respond competently and without long waiting times. This combination of range depth, quality assurance, and personal consultation makes ChemPUR a reliable sourcing partner for boron. Contact us for a non-binding quotation.
Is boron delivered worldwide?
In addition to standard quantities sufficient for many research and industrial applications, we supply boron and boron compounds in larger volumes as well as in customer-specific packaging. Shipping is international, enabling worldwide delivery. Applicable transport regulations for chemical substances are observed—particularly with regard to SVHC labeling, which is relevant for certain boron compounds such as boric acid. For deliveries to countries with special import requirements or for larger project quantities, early coordination is recommended to account for delivery times and customs requirements. Our team answers questions regarding shipping conditions, packaging regulations, and delivery deadlines directly and without detours.
What distinguishes boron from other elements?
Boron is primarily considered when a lightweight, hard, and functional material is required. It combines low weight with high hardness and is therefore suitable for applications in materials research, ceramic development, and wear-resistant materials. As a starting material for borides, boron carbides, and other boron-containing materials, boron plays an important role in high-performance materials. Boron may also be relevant in semiconductor-related applications or neutron-absorbing materials. Which boron grade is suitable depends on purity, form, and further processing. Our specialist team is pleased to support you in the selection.
Which boron compounds are available from ChemPUR?
In addition to elemental boron, ChemPUR offers various boron compounds for research, development, and technical applications. These include, among others, boric acid, boron carbides, boron nitrides, and boron oxides. Boric acid is available in several purity grades, from 99.5% to 99.999%. Boron carbides and boron nitrides are particularly interesting for materials science applications, for example when high hardness, temperature resistance, or ceramic properties are required.
Boron oxides, phosphates, and boron evaporation materials also complement the range for special applications in synthesis, materials research, or coating technology. If you require a specific boron compound, purity, or container size, please contact us. We will examine available options and support you in the appropriate selection.
For which applications is boron used?
In research and development, boron is primarily used where special material properties are required. These include high hardness, thermal stability, chemical resistance, and special electronic properties. In materials science, boron serves as a starting material for boron-containing high-performance materials, such as boron carbide or boron nitride. These materials are relevant for ceramic development, wear protection, high-temperature applications, and technical coatings. High-purity boron can also be used in semiconductor-related processes, for example when defined electrical properties are to be achieved.
Boron compounds such as boric acid, boron oxides, or borates also play an important role in analytics, glass and ceramic research, and in the development of functional materials. Depending on the application, purity, particle size, and chemical form are decisive. The appropriate boron grade depends on the desired material behavior and further processing. Our specialist team is pleased to support you in the selection.
Which forms does ChemPUR offer?
ChemPUR offers boron in several forms that differ according to processing and application. Elemental boron is available as amorphous or crystalline powder. Various particle sizes and purity grades are available, including amorphous boron powder with 2 µm, crystalline boron powder with 40 µm, and crystalline boron in coarser form.
For applications requiring a more compact form, ChemPUR offers crystalline boron pieces with 1–20 mm as well as boron rods with 5 mm and 10 mm diameter. These forms are particularly suitable when handling, defined geometry, or further processing are paramount. In addition to elemental boron, boron-containing compounds are also available in various forms. These include, among others, boron carbide as powder and nanopowder, boron nitride as powder, nanopowder, and rod, as well as boron oxide as powder or pieces. This enables you to select the appropriate boron form according to particle size, purity, geometry, and application.
In which purities is boron available from ChemPUR?
Which purity is suitable depends on how sensitive your application is to impurities and which form you require. Our specialist team is pleased to support you in selecting the appropriate boron grade. In our range you will find several purity grades: from 95–97% to 99.995%. Amorphous boron powder is available in both 95–97% and 99.9%. Crystalline boron powder is available, depending on the version, with 99%, 99.95+%, or 99.995% in dopant quality. For compact forms, ChemPUR offers crystalline boron pieces with 99% as well as boron rods with 99.5%. Boron compounds are also available in different grades: boric acid, for example, ranges from 99.5+% to 99.999%, boron oxide is available up to 99.999%.
