摘要
通过共沉淀法合成铌镁酸铅－钛酸铅介电陶瓷粉末，经８００℃焙烧后，Ｘ射线衍射研究表明几乎为单一钙钛矿相；经１０００℃烧结的陶瓷片其密度达到理论值的９６．７７％，２０℃介电常数可达２０９４０。
A coprecipitation method was used for preparation of lead magnesium niobate-lead titanate dielectric ceramic powder.X-ray powder diffraction revealed that the powder calcinated at 800℃ had only perovskite phase.The density of ceramic discs sintered at 1 000℃ was up to 96.77% the theoretical value,and its dielectric constant was reached 20 940 at room temperature.
