Oxide Ceramic Substrate

(1) Alumina ceramic matrix The ceramics with alumina as the main component are called alumina ceramics. Alumina has only one thermodynamically stable phase. Alumina ceramics include high-purity alumina ceramics, 99 alumina ceramics, 95 alumina ceramics, 85 alumina ceramics, etc.

(2) Zirconia ceramic matrix The ceramics with zirconia as the main component are called zirconia ceramics. Zirconia has a density of 5.6-5.9g/cm3 and a melting point of 2175°C. Stable zirconia ceramics have low specific heat capacity and thermal conductivity, good toughness and good chemical stability. It has acid and alkali resistance at high temperature.
