Alumina ceramic bulletproof plate body armour car body protection higher hardness military technology
product name:Alumina ceramic bulletproof plate
Introduction of alumina ceramic bulletproof plate:
The reason why ceramics can be bulletproof is their high specific stiffness, high specific strength and chemical inertness in many environments. It is better than the metal in that the metal material will produce plastic deformation and absorb energy when resisting the impact of the warhead, while the ceramic almost does not produce plastic deformation, and relies on its own high strength and high hardness to passivate or even break the warhead. The ceramic surface smashes and absorbs the energy of the high-speed warhead in the process of forming a small and hard fragment area. Therefore, the application of advanced ceramics in armored systems is very attractive, and it has become a kind of protective armor widely used in bulletproof clothing, vehicles and aircraft.
The molecular formula of alumina is Al2O3, white solid, and the most common crystalline states are α-Al2O3, β-Al2O3 and γ-Al2O3. The structure of α-Al2O3 is the most stable ( also known as corundum ). At high temperatures above 1300 °C, other phases are almost completely transformed into α-Al2O3, which is the main component of alumina bulletproof ceramics.
