一种Ni2O3-SnO2-Zn2SnO4压敏复合陶瓷材料及其制备方法
摘要：
一种Ni2O3-SnO2-Zn2SnO4压敏复合陶瓷材料，由SnO2粉料、Zn2SnO4粉料和Ni2O3粉料经混合压制，并烧结制成，所述SnO2粉料、Zn2SnO4粉料和Ni2O3的摩尔比为80：20：x，其中x的取值为0.15-0.6；本发明通过Ni2O3的掺杂，可以有效调节SnO2-Zn2SnO4复合陶瓷的压敏电压梯度，使得其在不改变器件尺寸的条件下能够在低电压范围内大多数电压保护领域得到应用。
摘要（英）：

The invention discloses a Ni2O3-SnO2-Zn2SnO4 pressure-sensitive composite ceramic material, which is prepared by mixing, pressing, and sintering SnO2 powder, Zn2SnO4 powder, and Ni2O3 powder, wherein the mole ratio of SnO2 powder to Zn2SnO4 powder to Ni2O3 powder is 80:20:x, and x is in a range of 0.15 to 0.6. By doping Ni2O3, the pressure-sensitive voltage gradient of SnO2-Zn2SnO4 composite ceramic can be effectively adjusted, and thus the provided Ni2O3-SnO2-Zn2SnO4 pressure-sensitive composite ceramic material can be used in most voltage protection fields in a lower voltage range without changing the size of devices.
