Blue white BN boron nitride coating manufacturers introduce the material properties and material structure knowledge of boron nitride
How much do you know about the material properties and material structure of boron nitride? Follow the editor of Blue white BN boron nitride coating manufacturers to have a simple understanding!
1. Material characteristics
Boron nitride has chemical resistance properties and is not corroded by inorganic acids and water. The boron-nitrogen bond is broken in the hot concentrated alkali. Above 1200℃, it will be oxidized in the air. It begins to decompose at about 2700°C under vacuum. Slightly soluble in hot acid, insoluble in cold water, relative density 2.29. The compressive strength is 170MPa. The maximum operating temperature is 900°C in an oxidizing atmosphere, while it can reach 2800°C in an inactive reducing atmosphere, but the lubrication performance is poor at room temperature. Most of the properties of boron nitride are better than carbon materials. For hexagonal boron nitride: low friction coefficient, good high temperature stability, good thermal shock resistance, high strength, high thermal conductivity, low expansion coefficient, high electrical resistivity, corrosion resistance, microwave or transparent Infrared.
2. Material structure
Hexagonal boron nitride crystals, the most common graphite lattice, also have amorphous variants, in addition to the hexagonal crystal form, boron nitride has other crystal forms, including: rhombohedral boron nitride, cubic boron nitride, fiber Zinc-type boron nitride.
In summary, the editor of Blue white BN boron nitride coating manufacturers tells: a brief introduction to the material properties and material structure of boron nitride.
