The main reason why ceramics are used as bulletproof materials is its high hardness, and the weight is much lighter than steel under the same bulletproof effect. For people who often wear bulletproof vest, weight is an important consideration. Another advantage of ceramic materials relative to steel, Ceramic bulletproof plate can absorb the energy of bullet impacts, and the steel bullet-proof plate will rebound the bullet when the bullet hits, which may cause harm to people around you.

THREE DIFFERENT BULLETPROOF CERAMIC MATERIALS 

Since the 21st century, bulletproof ceramics have developed rapidly and there are many types, including alumina, silicon carbide, boron carbide, silicon nitride, titanium boride, etc., among which alumina ceramics (Al2O3), silicon carbide ceramics (SiC), carbide Boron ceramics (B4C) are the most widely used.

Alumina ceramics (Al2O3) has the highest density, but its hardness is relatively low, processing threshold is low, and the price is relatively cheap.

The covalent bond of silicon carbide (SiC) is extremely strong, and it still has high-strength bonding at high temperature. This structural feature gives silicon carbide ceramics excellent strength, high hardness, wear resistance, corrosion resistance, high thermal conductivity, and good heat resistance. And shock resistance and other properties; at the same time, silicon carbide ceramics (SiC) are moderately priced and cost-effective. It is one of the most promising high-performance body armor protection materials.

Boron carbide (B4C) is currently known as a superhard material whose hardness is second only to diamond and cubic boron nitride. The hardness is as high as 3000 kg/mm2; the density is only 2.52 g/cm3, which is 1/3 of that of steel. Boron carbide ceramics (B4C) have the lowest density and the highest strength among these types of ceramics. At the same time, it has high requirements on processing technology and requires high temperature and high pressure sintering, so its price is also the most expensive of several ceramics.
