Mullite has a high melting point, good thermal stability at high temperature, better mechanical properties,its mechanical properties increase with the increase of temperature, lower dielectric constant and thermal expansion coefficient, good resistance to heat shock performance and air tightness. Due to its excellent physical and chemical properties, molite ceramics are widely used in high temperature structural materials (such as: crucible, thermocouple and protective pipe, etc.), electronic packaging materials (such as induction coil capacitor, molite ceramic substrate, etc.).
