Product Overview
Description
Bulletproof ceramic armor has become a fast-growing industry internationally due to the war on terrorism. Whether it is for human body protection or armor protection for vehicles, aircraft, and ships, advanced ceramics have many advantages over conventional materials, mainly including light weight, high hardness, and uniform control of microstructures, so they can withstand more serious threats. Among the main bulletproof ceramic materials such as boron carbide (B4C), silicon carbide (SiC) and other high-hardness ceramic materials, boron carbide ceramics are light weight, high hardness (second only to diamond and cubic boron nitride), plus elasticity. The high modulus makes it a good choice for military armor. Silicon carbide ceramics have become the mainstream products of international bulletproof ceramics in recent years because of their high hardness, good bulletproof effect and low manufacturing cost.
