Advanced ceramics is different from traditional ceramics.Traditional ceramics include clay products, silicate glass and cement,but advanced ceramics are ceramic products made from materials like aluminum oxide (Al2O3), zirconium oxide(ZrO2), silicon carbide(SiC), silicon nitride(Si3N4), boron carbide(B4C) etc. Based on the special property, advanced ceramics are usually used for high temperature application of Electronics Industry, Machinery Industry, Chemical Industry, Metallurgical Industry, Aerospace Industry etc.
Advantages of Advanced Ceramics
*High temperature resistance up to 1700℃
*Some kinds of advanced ceramics have high thermal shock resistance
*Corrosion resistance
*Good wear resistance
*Good dielectric properties
