Boron Nitride (BN)

Hexagonal boron nitride is one kind of loose, lubricious and hygrometric white powder. Its theoretical density is 2.27/cm3, Mosh hardness is 2. Its mechanical strength is lower, but higher than the graphite’s . It has not the exact melting point , but sublimates at 3000 ℃ in 0.1Mpa nitrogen gas . The highest using temperature is 2800 ℃ in nitrogen or argon gas, but below 1000 ℃ in oxygen.

It has lower thermal expansion coefficient and higher thermal conductive rate , so its heat-resisting shaking ability is fine . The loop time from 1200 ℃ to 20 ℃ is more than one hundred and the BN has not been destoried .

Boron nitride belongs to hexagonal crystal system , its crystal structure is similar to graphite , so it is also called white graphite . B and N atom arrange to six-angle ring network alternately. The atoms in layer bond each other covalently and strongly, but the atoms between layers bond with molecular bond, so it is weak and ease to break. The atom space of B-N in each layer is 0.142nm, and the elastic modulus E is 910Gpa. But between layers it is 0.335nm and 30 Gpas respectively. Not only the structure of BN is consistent with graphite but also the lattice constant is similar.
