MST varistor grade zinc oxide powder has good thermal stability and thermal conductivity, high boiling point and low thermal expansion coefficient. The band gap is 3.2-3.4eV. ZnO should be an insulator at room temperature. ZnO is decomposed at high temperature. Excessive zinc enters the gap due to ionization, forming interstitial ions, causing shared movement of electrons in the structure, forming an n-type semiconductor, which is an important raw material for the production of zinc oxide varistors.
