Introduction of Boron carbide ceramics
Boron carbide ceramics is a class of ceramics which the main chemical ingredient is boron carbide.The chemical formula of boron carbide is B4C, it belongs to hexagonal diamond crystal, there are 12 boron atoms in the unit cell, lattice parameter co = 1.212nm, ao = 0. 56nm. Crystal structure exists atom which can accommodate up to 0.18nm diameter, so it can remain the lithium or helium atoms within the crystal structure.
