Properties of Sensitive Materials Mainly Composed of ZnO

Sensitive materials mainly composed of ZnO and their multi-functional properties were investigated. The temperature extent of linear resistance, non-linear deviation and endurance ability of surge energy were further discussed. The effect of Mg2+, Al3+ and Si4+: which could be solid solutioned in ZnO grain and the function of Y3+ ion segregated out in grain boundary were studied as well. The function of Ti was analyzed emphatically.
