【Abstract】 In this paper we study thd effect of the different proportion of raw materials on the structure and thermosensitive character of SnO₂-ZnO ceramics. Changing the proportion of SnO₂and ZnO contents, we can make the material with different heat sensitivity to satisfy the need of designs. The resistivity of material at room temperature is from 10^-2Ω-cm to 10⁶Ω-cm, its B value is between 200 to 22,000, and its operating temperature is from 77K to 1,200K.更多还原
