Method for preparing ZnO piezoresistor by pre-synthesizing Zn7Sb2O12
The invention discloses a method for preparing a ZnO varistor by pre-synthesizing Zn7Sb2O12, which comprises the following steps of: uniformly mixing all Sb2O3 and part of ZnO in raw materials according to a molar ratio of 0.8: 7-1.2: 7, then pre-sintering at 980-1060 DEG C to form a Zn7Sb2O12 spinel phase, and mixing the Zn7Sb2O12 spinel phase with the rest ZnO and other raw material components as a raw material to prepare the ZnO varistor. On the basis that the original formula of the ZnO varistor is not changed and harmful impurities are not introduced, the sintering temperature can be reduced, the electrical property of the varistor is ensured, and the preparation method has the characteristics of simple process and low cost and is suitable for industrial large-scale production.
本发明公开了一种Zn7Sb2O12预合成制备ZnO压敏电阻的方法，先将原料中的全部Sb2O3和部分ZnO按摩尔比0.8：7‑1.2：7混合均匀，然后在980‑1060℃预烧形成Zn7Sb2O12尖晶石相，再将Zn7Sb2O12尖晶石相与剩余的ZnO和其他原料成分混合作为原料进行ZnO压敏电阻的制备。本发明在不改变ZnO压敏电阻原本配方和不引入有害杂质的基础上，能够降低烧结温度，保证压敏电阻的电学性能，并且具有工艺简单和成本低廉的特点，适宜工业化大规模生产。
