六方晶窒化ホウ素を理解する

Boron nitride is made up of nitrogen and boron atoms in the crystal, the crystal structure can be divided into: hexagonal boron nitride (HBN), dense rows of hexagonal boron nitride (WBN) and cubic boron nitride, the crystal structure of hexagonal boron nitride have similar graphite layer structure, loose, lubrication, easy absorption of moisture, light and other traits of white powder, say again so "white graphite. 

Hexagonal boron nitride has the same expansion coefficient as quartz, but ten times the thermal conductivity. Also has good Chemicalbook lubricity at high temperature, is an excellent high temperature solid lubricant, has strong neutron absorption capacity, chemical stability, chemical inertia to almost all molten metals. 

六方晶窒化ホウ素は冷水に不溶です。 水を沸騰させると、加水分解が非常に遅くなり、少量のホウ酸とアンモニアが生成されます。 室温では弱酸や強塩基と反応せず、熱酸にわずかに溶けます。 さまざまな無機酸、塩基、塩溶液、有機溶剤に対してかなりの耐食性があります。
