Alumina ceramics with a content of 99% can be used as bulletproof ceramics.
Because of its high hardness and strength, When the bullet hits the ceramic surface, it will have a strong impact，this impact extends to ceramics and bullets.Under this impact,The ceramic is slightly broken, resisting the penetration of the bullet，The ceramic absorbs the kinetic energy of the bullet by micro-fragmentation, so as to achieve bulletproof. The strength of bulletproof ceramics is steel armor 3-4 times higher than the protection factor of steel armor.
