What is Boron Nitride CAS 10043-11-5?

Boron Nitride CAS 10043-11-5 is a boron-nitrogen compound with the formula BN. Hexagonal boron nitride, or h-BN, has a graphite-like layered structure but is white and electrically insulating.

How does hexagonal Boron Nitride compare with graphite?

Both have layered structures and good lubricity, but h-BN is an electrical insulator while graphite conducts electricity. h-BN is also white, which makes it useful in cosmetics and light-colored materials where graphite would be unacceptable.

What cosmetic benefits does Boron Nitride provide?

Cosmetic-grade Boron Nitride is used as a slip agent, mattifier, and oil absorber in pressed and loose powders, foundations, and creams. It improves spreadability and gives a soft, silky feel.

What electronic and thermal applications use Boron Nitride?

Because it combines high thermal conductivity with high electrical resistance, h-BN is used in thermal interface fillers, thermally conductive plastics and rubbers, high-temperature insulation, and release or mold-wash applications.

What grade and particle-size factors should buyers check?

Key factors include BN purity, free boron oxide content, particle-size distribution, tap density, and application-specific grade. Cosmetic, electronic, and industrial grades may prioritize different combinations of these properties.

Product Description

Boron Nitride, CAS 10043-11-5, is a boron-nitrogen compound with the formula BN.

Synonyms: Hexagonal Boron Nitride; h-BN; White Graphite; Boron mononitride; BN powder.

CAS: 10043-11-5.

Hexagonal boron nitride has a graphite-like layered structure but is white and electrically insulating.

It is chemically inert, non-toxic and stable up to about 900 °C in air and 2000 °C in inert atmosphere.

It combines high thermal conductivity with high electrical resistivity, and provides excellent lubricity.

It is used as a high-temperature lubricant additive in greases and oils for extreme-pressure and high-heat environments.

It is used as a mold-release agent in metal casting and glass molding to prevent sticking.

Cosmetic grade is used in makeup as a slip agent, mattifier and oil absorber for a soft, silky feel.

It is used as a thermally conductive but electrically insulating filler in thermal pads, silicone sheets and epoxy resins.

It is sintered to produce evaporation boats and ceramic parts for semiconductor processing.

It is used in anti-corrosion and anti-stick coatings for industrial machinery.

It is also used in thermally conductive plastics, rubbers, high-temperature insulation and release applications.

Confirm appearance, crystal structure, BN purity, free B2O3, particle size, tap density, true density, melting point, thermal conductivity, electrical resistivity and solubility.

Store in a strictly dry, cool, well-ventilated warehouse away from direct sunlight.

Keep the container tightly sealed immediately after use, as the powder can slightly absorb moisture over time.

Confirm packaging with the requested quantity and destination requirements.
