Product Description
Si3N4 Silicon nitride ceramic pot, High temperature resistant ceramic parts
Silicon Nitride ceramic has the advantages of high hardness and low density, and is very strong in the defense of kinetic energy projectile and ammunition fragment. Now it has become a kind of protective armor widely used in bullet-proof clothes, vehicles, aircraft and other equipment. This type of ceramic composite armor is not only resistant to conventional ammunition, but also to neutrals and anti-tank missiles.
