Zirconia，with its molecular formula of ZrO2, is the main oxide of zirconium. Natural minerals containing zirconium mainly include incline zircon and zircon and so on. Zirconia is usually a white odorless and tasteless crystal, insoluble in water, hydrochloric acid and dilute sulfuric acid, chemically stable, and features high hardness, high melting point, high resistivity, high refractive index and low thermal expansion coefficient characteristics, has been widely used in wet-resistant ceramics, refractory materials, machinery, electronics, optics, aerospace, biology, chemistry and other fields. Our common artificial drills and dental implants are also based on zirconia as the main material.
The ceramic materials feature low density and high values of mechanical properties such as hardness, Young's modulus, and strength. Bulletproof ceramic materials include alumina (Al2O3), silicon carbide (SiC), and boron carbide (B4C). Lightweight composite armour systems composed of a B4C ceramic panel and composite back panel have excellent bulletproof performance and are used to resist attacks from armour-piercing incendiary projectiles. Nextgen Advanced Materials is a mature supplier of providing B4C panels for customers around the world. According to user’s feedback and a comparison with the experimental results, our products have passed IV grade protection tests and are reliable in various environment. A lot of simulations have proved the ballistic performance our B4C composite armour.
1. Alumina ceramic is a ceramic material mainly composed of alumina (Al2O3), which is used for thick film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic cleaning is required. Alumina ceramics are a kind of ceramics with a wide range of uses.
