What is boron nitride?

Boron nitride is a crystal composed of nitrogen atoms and boron atoms. It has a white solid appearance and the chemical formula is BN. The chemical composition is 43.6% boron and 56.4% nitrogen.
Properties of boron nitride 
Boron nitride is resistant to chemical attack and is not eroded by inorganic acid and water. The boron - nitrogen bond is broken in the thermally concentrated alkali. Above 1200℃, oxidation begins in air, melting point is 3000℃, slightly below 3000℃, sublimation begins. It starts to decompose at about 2700℃ in vacuum, slightly soluble in hot acid, insoluble in cold water, relative density 2.25 Compression strength is 170MPa.The maximum operating temperature is 900℃ in the oxidizing atmosphere, and up to 2800℃ in the inactive reducing atmosphere, but poor lubrication performance at room temperature.
The action of boron nitride
The application of boron nitride is very wide, such as metal mold release agent and metal wire drawing lubricant; Special electrolytic and resistive materials at high temperature; High temperature solid lubricant, extruded anti-wear additive, additive for the production of ceramic composites, refractory material and antioxidant additive; Thermal shielding materials in aerospace; All kinds of laser anti-counterfeiting aluminum, trademark hot stamping materials, all kinds of cigarette labels, beer labels, packaging boxes, cigarette packaging aluminum; Cosmetics used for lipstick filling, non-toxic and lubricious, and shiny; Metallurgically, separation rings for continuous cast steel, grooves for amorphous iron, release agents for continuous cast aluminum ;All kinds of fresh aluminized packaging bags and so on.
