Nitride Powder

Hexagonal Boron Nitride BN Powder CAS 10043-11-5

Item No.: Tr-BN
Hexagonal boron nitride is also called white graphite. Nitrogen and boron in hexagonal boron nitride also form a hexagonal network layer, which overlaps each other to form a crystal.
Purity: 99%
Particle Size: 100nm, 500nm, 3-5um
Boron Nitride Properties
About Hexagonal Boron Nitride BN Powder CAS 10043-11-5:
Hexagonal Boron Nitride(h-BN), an advanced synthetic ceramic, combines a number of useful thermal, electrical, physical and chemical properties in one unique material. Boron Nitride powders, also referred to as white graphite are non-abrasive, white powders with a hexagonal platy crystal structure similar to graphite, but with a much higher oxidation resistance at 800ºC. Boron Nitride powders have high thermal conductivity, low coefficient of friction, high dielectric constant and are chemically inert.
Boron nitride industrial powder is a pure white ceramic material with a hexagonal crystal structure similar to graphite. Boron nitride can withstand temperatures exceeding 2,000°C, and depending on the grade, its dielectric strength is close to 1000 volts/mil. Boron nitride is hot-pressed in the form of billets, which can be easily processed into rods, bars, plates and even customized shapes.

Product Performance of Boron Nitride BN powder:
Boron nitride is a most simple new type of macromolecular material with both hexagonal and cubic crystal shapes. 
It is a kind of product with high temperature-resisting, corrosion-resisting, high insulating and good lubricity.
Its oxidation-resisting temperature can reach 1000°C and possesses also good lubricity in high temperature, so it is 
a  kind of good high-temperature solid lubricants.

How is Hexagonal Boron Nitride BN Powder CAS 10043-11-5 produced?
Hexagonal BN (hBN) is commonly referred to as "white graphite". It is an artificial ceramic made by reacting boric acid or boron oxide with nitrogen at a temperature above 1600°C. The resulting product is a smooth white powder with excellent high-temperature stability (oxidation resistance at 850°C) and lubricating properties.

Applications of Boron Nitride BN Powder:
Hexagonal boron nitride is white (clean appearance), non-toxic and non-conductive. It is an excellent substitute for other commonly used lubricants in metal processing (such as graphite, molybdenum disulfide, organic wax and oil). In most cases, boron nitride can greatly improve the efficiency of these applications.
Used as a high-temperature solid lubricant, extrusion antiwear additive, additive for ceramic composite production;
Used for special electrolysis and resistance materials under high-temperature conditions;
Thermal insulation materials used in aerospace;
Used as a mold release agent for metal forming and a lubricant for metal wire drawing;
Used for molten metal crucible; radiator and high-temperature insulator;
Used as a raw material for cosmetics.
