Boron Nitride (BN) Products

Boron nitride (BN) is a crystal composed of nitrogen atoms and boron atoms. The chemical composition is 43.6% boron and 56.4% nitrogen with four different variants: hexagonal boron nitride (HBN), rhomboid boron nitride (RBN), cubic boron nitride (CBN), and fiber zinc ore boron nitride (WBN).

Boron nitride resists chemical erosion and is not eroded by inorganic acid and water. The boron-nitrogen bond is disconnected in a hot concentrated base. Over 1,200 ℃ began to oxidize in the air. About 2700 ℃ starts the decomposition at the vacuum. Microsoluble in thermal acid, insoluble in cold water, with a relative density of 2.29. Compression strength is 170MPa. The maximum use temperature is 900 ℃ in an oxidation atmosphere, compared to 2800 ℃ in an inactive reduction atmosphere, but with poor lubrication performance at room temperature. Most the boron nitride performs better than carbon materials. For hexagonal boron nitride: very low friction coefficient, good high-temperature stability, high heat shock resistance, high strength, high thermal conductivity, low expansion coefficient, large resistivity, corrosion resistance, permeable microwave or infrared transmission.
