Advanced ceramic materials active in military equipment
Advanced ceramics: According to chemical composition, they can be divided into oxide ceramics, nitride ceramics, carbide ceramics, boride ceramics, silicide ceramics, fluoride ceramics, sulfide ceramics, etc. According to performance and purpose, it can be divided into two categories: functional ceramics and structural ceramics. Functional ceramics are mainly based on the special functions of materials, with characteristics such as electrical properties, magnetism, biological properties, thermal sensitivity, and optical properties. They mainly include insulation and dielectric ceramics, ferroelectric ceramics, piezoelectric ceramics, semiconductors and their sensitive ceramics, etc; Structural ceramics are mainly based on the mechanics and structural uses of materials, with characteristics such as high strength, high hardness, high temperature resistance, corrosion resistance, and oxidation resistance.
Functional ceramics account for approximately 70% of the market share in advanced ceramics, while the rest are structural ceramics.
Ceramic materials and ceramic matrix composites will be used in armor
Such as bulletproof vests, protective layers for aircraft and armored vehicles, etc. A bulletproof vest mainly consists of a jacket and a bulletproof layer. The bulletproof layer can absorb the kinetic energy of a bullet or fragment, and has a significant protective effect on low-speed bullets or fragments. It can reduce damage to the chest and abdomen of the human body by controlling certain depressions. Hot pressed boron carbide and silicon carbide ceramic matrix composites can be used to manufacture sturdy anti impact armor plates. China is one of the three largest producers of bulletproof vests in the world. In the international market, the price of our defense bulletproof vests is about $500, while the price of bulletproof vests in other countries is around $800. China has an advantage in manufacturing costs.
