Alumina vs silicon ceramic armor plate
Ceramic bulletproof sheet (bulletproof plate) is an important part of bulletproof equipment. At present, silicon carbide ceramics and high alumina ceramics are the two most demanded bulletproof ceramic materials in the market. Because the bulletproof process takes place in a very short time, bulletproof ceramics require more properties, such as density, porosity, hardness, fracture toughness, elastic modulus, sound velocity and mechanical strength, etc. Chemshun ceramic alumina ballistic sheet is made of ultra-fine alumina powder as the main material. The purity of α-Al₂O₃ exceeds 99%, the density is ≥3.9g/cm³, the porosity is close to zero, and the water absorption rate does not exceed 0.02%. The hardness can reach above HRA88, which is the first choice material for bulletproof ceramics. The bulletproof level exceeds the American standard level 3. At the same time, it also meets the needs of customers for silicon carbide bulletproof ceramics. The density is ≥3.1g/c...
