BORON NITRIDE- ▸ Solid lubricant: High-temperature, graphite-like dry lubricant and release agent.
- ▸ Thermal management: Thermally conductive, electrically insulating filler.
- ▸ Refractory/foundry: Crucibles, coatings and high-temperature foundry use.
- ▸ Cosmetic slip: Soft-focus, slip and absorbent powder in color cosmetics.
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Boron Nitride (BN, CAS 10043-11-5) is a refractory boron-nitrogen ceramic whose hexagonal form (hBN) has a layered, graphite-like structure. It is used as a high-temperature solid lubricant and release agent, a thermally conductive yet electrically insulating filler, a refractory and foundry material, and as a slip and soft-focus agent in cosmetics.
Frequently Asked Questions
What is boron nitride used for?
Boron nitride (BN, CAS 10043-11-5) is a boron-nitrogen ceramic. Its hexagonal form (hBN) is used as a high-temperature solid lubricant and release agent, as a thermally conductive but electrically insulating filler for thermal management, in refractory and foundry applications such as crucibles and coatings, and as a slip and soft-focus agent in color cosmetics.
What is another name for boron nitride?
Boron nitride is commonly referred to by its formula, BN, and the layered, graphite-like form is called hexagonal boron nitride or hBN (sometimes called 'white graphite' because of its graphite-like structure).
Why is boron nitride both thermally conductive and electrically insulating?
Hexagonal boron nitride has a layered structure similar to graphite, which conducts heat efficiently along its planes, but unlike graphite its electrons are localized in the boron-nitrogen bonds, so it does not conduct electricity. This combination is why hBN is used as a filler in thermal-management compounds that must remain electrically insulating.
What is the HS code for boron nitride?
Boron nitride is classified under HS heading 2850.00 (hydrides, nitrides, azides, silicides and borides). Confirm the destination-country subheading with your customs broker before import.
How is bulk boron nitride powder supplied?
RawSource supplies boron nitride powder in industrial bulk packaging for lubricant, refractory, thermal-management, and cosmetic formulators. Grades differ in particle size and purity by application, so specify your use and target volume; a CoA and SDS are provided with each shipment and pricing is quoted per order.
