Silicon-doped zinc oxide varistor composite powder and preparation method thereof
The invention discloses silicon-doped zinc oxide varistor composite powder and a preparation method thereof, and belongs to the technical field of preparation of electronic ceramic materials. The method adopts a silane hydrolysate as a dispersing agent of a zinc oxide varistor formula material, and comprises the following specific steps: hydrolyzing silane in an acidic alcohol-water mixed system to obtain a stable silane hydrolysate, then adding the zinc oxide varistor formula material into the silane hydrolysate, dispersing and grinding, and finally carrying out spray granulation. The silicon-doped zinc oxide varistor composite powder prepared by the method can be pressed and molded without adding an organic adhesive, and a zinc oxide varistor with good comprehensive performance can be obtained.
本发明公开了一种硅掺杂氧化锌压敏电阻复合粉体及其制备方法，属于电子陶瓷材料制备技术领域。该方法采用硅烷水解液作为氧化锌压敏电阻配方材料的分散剂，具体步骤为：先将硅烷在酸性醇‑水混合体系中水解获得稳定的硅烷水解液，然后将氧化锌压敏电阻配方材料加入硅烷水解液中进行分散研磨，最后进行喷雾造粒。该方法制备的硅掺杂的氧化锌压敏电阻复合粉体无需加入有机粘合剂即可压制成型，可获得综合性能良好的氧化锌压敏电阻。
