Zinc oxide pressure-sensitive ceramic material and preparation method thereof
The invention provides a zinc oxide pressure-sensitive ceramic material and a preparation method thereof. The method comprises the following steps: 1) preparing a ZnO/Al2O3 composite material by usinga hydrothermal method; 2) selecting raw materials of ZnO, the ZnO/Al2O3 composite material, Co2O3, MnO2, Cr2O3, Bi2O3, Sb2O3, SiO2, Y2O3 and Sc2O3, uniformly mixing the raw materials, and then carrying out ball milling on the mixture; and 3) carrying out spark plasma sintering on the ball-milled mixture to obtain the zinc oxide pressure-sensitive ceramic material. Zinc oxide prepared by the method is good in binding property with aluminum oxide, the uniform distribution uniformity of aluminum oxide is high, the sintering temperature of the pressure-sensitive ceramic is low, and a sintered body has a grain structure with high uniformity, so that the zinc oxide pressure-sensitive ceramic material has excellent nonlinear electrical properties.
本发明提供一种氧化锌压敏陶瓷材料及其制备方法，该方法包括以下步骤：1)利用水热法制备ZnO/AlO复合材料；2)选取原料ZnO、ZnO/AlO复合材料、CoO、MnO、CrO、BiO、SbO、SiO、YO和ScO混合均匀，然后将混合物进行球磨；3)将球磨后的混合物进行放电等离子烧结，得到所述氧化锌压敏陶瓷材料。这种方法制备的氧化锌与氧化铝结合性好，氧化铝均匀分布均匀性高；并且压敏陶瓷烧结温度低，烧结体具有均匀性高的晶粒组织，因此具有优异的非线性电性能。
