| titleOfInvention | A kind of preparation method of composite nanometer ZnO varistor ceramic powder |
| abstract | The invention relates to a ZnO pressure-sensitive ceramic material, in particular to a preparation method of a composite nanometer ZnO pressure-sensitive ceramic powder. Soluble zinc salt, bismuth salt, cobalt salt, and manganese salt are used as raw materials, respectively configured into aqueous solutions, calculated by mole percentage, according to 95% ZnO, 3% Bi 2 O 3 , 1% CoO, 1% Mix the ratio of MnO and stir evenly; slowly add ammonia water to the mixed solution obtained in step (1), adjust the pH at 8~8.5 to obtain a mixed solution, continue to stir until mixed evenly; filter the precipitate obtained in step (2) , and fully washed with deionized water and ethanol to remove impurities, put the obtained precursor in water or ethanol medium to reflux for 2~8h, and control the reflux temperature at 70~80°C; finally, filter the powder obtained by reflux, and use Ionized water and ethanol are fully washed to remove impurities, and finally dried in a vacuum oven, and the nanocomposite ZnO powder is obtained after grinding. |
