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

Boron carbide bulletproof ceramics Carbonized bridges are the superhard materials of bridges and cubic boron nitride among the currently known materials. Among these ceramics, they have the highest ceiling and the lowest density. The stairs are 2.52g/cm3, which is 1/3 of steel; the elastic modulus High, low thermal expansion coefficient and high thermal conductivity. In

What is the bulletproof principle of ceramic materials? The basic principle of armor protection is to consume the warhead, decompose the projectile and render it harmless. Similar to traditional engineering materials, metal materials absorb energy through plastic deformation of the structure, while ceramic materials absorb energy through micro-decomposition processes. The energy absorption process of bulletproof

What are the material performance requirements for bulletproof ceramics Due to the brittleness of the ceramic itself, it fractures rather than plastically deforms when impacted by projectiles. First, under the action of the winch, fracture occurs at inhomogeneous places such as bridges and grain boundaries. Therefore, to minimize stress concentrations, armor ceramics should be high-quality

The difference between boron carbide and boron oxide Boron carbide, also known as black diamond, has a molecular formula of B₄C and is usually a gray-black powder. It is one of the three hardest materials known (the other two are diamond and cubic boron nitride) and is used in tank armor, bulletproof vests and many

The difference between boron carbide and silicon carbide Although boron carbide and silicon carbide are both abrasives, and there is only one difference, boron carbide and silicon carbide are two completely different products. 1. The main ingredients are different The main component of boron carbide is B4C The main component of silicon carbide SIC 2.
