Common bulletproof ceramic materials
There are many bulletproof ceramic materials. These are the most commonly used ones, including alumina, silicon carbide, boron carbide, silicon nitride, titanium boride, etc. Among them, alumina ceramic (Al2O3), silicon carbide ceramic (SiC), boron carbide ceramic ( B4C) is the most widely used. Alumina ceramics have the highest density, but relatively low hardness, low processing threshold, and low price. According to purity, they are divided into 85/90/95/99 alumina ceramics, and the corresponding hardness and price also increase in sequence.
