This product is mainly applied in body protection and vehicle protection. Using high purity Al2O3 powder as raw material, we mold alumina products by large-tonnage and two-sided pressing machine, then sinter them in automatic controlled ultra-high temperature kilns. The alumina bulletproof ceramic produced by our company has been widely used in the protection of special vehicles and military projects.
