Effect of Oxide Semiconductor on the Performance of Electric Porcelain Glaze

With the rapid development of electric power industry, the market demand for electric porcelain is increasing day by day. In order to produce electric porcelain insulator with better performance and better quality, improving the performance of electric porcelain glaze is also a problem that needs to be solved. ZnO and SnO2 are common semiconductors. This paper mainly studies the addition of 10, 20, and 30% ZnO and SnO2 powders to electric porcelain white glaze (produced by an electric porcelain factory in Jiangxi Province). By observing the changes of glaze properties after the addition of oxide powder with different contents, the changes of glaze properties after sintering, and whether the network structure is formed under the electron microscope. Investigate the feasibility of preparing semiconductor glaze by adding ZnO and oxide powders directly to electric porcelain white glaze. The results show that when ZnO and SnO2 powders are added to the primary glaze, the glaze viscosity will increase. When the oxide content is 30%, the glaze viscosity is 30% higher than that when the oxide content is 20%, and the glaze viscosity is 50% higher than that of the primary glaze. At the same time, the Zeta potential value becomes smaller and the stability of the slurry becomes worse.
