Silicon Carbide Ceramic Bullet Proof
Silicon Carbide Ceramic Bullet Proof,Ceramic Armor for Ballistic
Protection of Personnel, Vehicles and Assets
Silicon carbide (SiC), also known as carborundum, is a compound of
silicon and carbon with a chemical formula SiC. It occurs in nature
as the extremely rare mineral moissanite. Silicon carbide powder
has been mass-produced since 1893 for use as an abrasive. Grains of
silicon carbide can be bonded together by sintering to form very
hard ceramics which are widely used in applications requiring high
endurance, such as car brakes and ceramic plates in bulletproof
vests. Electronic applications of silicon carbide as light emitting
diode and detector in early radios have been demonstrated around
1907, and nowadays SiC is widely used in high-temperature
semiconductor electronics. Large single crystals of silicon carbide
can be grown by the Lely method; they can be cut into gems known as
"synthetic moissanite". Silicon carbide with high surface area can
be produced from SiO2 contained in plant material.
