As an advanced high-tech material, ceramic material has the characteristics of high strength, high hardness, corrosion resistance, high wear resistance and light weight. It is very suitable for lightweight upgrade applications. It has a strong defense capability for kinetic energy ammunition and ammunition fragments. Ceramic armor can not only resist the attack of conventional ammunition, but also withstand the attack of neutron bomb and anti-tank missile. Among them, the performance index, batch stability and consistency of ballistic-proof ceramic materials in hard composite armor deck are particularly critical, which determine and affect the protection safety and reliability of tank armor.
