摘　　要：研究了利用稀土掺杂TiO2制备防污闪材料涂层,结果表明掺杂0.5%的硝酸钇、涂层镀2层、在550℃下灼烧2h的样品防污性能最好。研究了利用稀土改性TiO2防污闪材料涂层在电瓷中应用的涂覆工艺路线,结果表明涂覆防污闪涂层的电瓷样品较普通电瓷防污闪性能提高30%。还分析了稀土改性TiO2防污闪材料涂层提高防污闪电压的原因。In this paper,rate—earth doped TiO2 anti—pollution flashover coating is prepared.The results show that the sample's anti—pollution flashover performance is best by doping Y2O5 with addition of 0.5% with double—layer and incandesce time 2h under 500℃.The process route of coating is researched.The results show that artificial pollution voltage is improved 30%.In addition,the principle of the improving the anti—pollution flashover voltage of the porcelain with rate—earth doping is analyzed.
