摘　　要：为了满足生产550kV/20kN以上棒形产品的要求,对高性能电瓷材料配方进行了研究,在配方中添加α-Al2O3,可提高电瓷材料强度;添加碱土金属元素化合物,可起到强熔剂与“压碱效应”的作用。研制出的等静压电瓷材料具有较低的烧成温度和良好的机、电、热性能;瓷弯曲强度184MPa、瓷上釉弯曲强度230MPa、电气强度32kV/mm、冷热急变性200K。A combosition of high performance porcelain body material was development for manufacturing solid core post insulators of 500 kV/20 kN and above, α-Al2O3 was introduced for enhancing mechanical strength and alkaline-earth metal components were introduced as flux and ＂alkaline-restrainer＂. The developed porcelain material used for isostatic pressing has low sintering temperature and high mechanical, electrical and thermal performances; bending strength of porcelain body 184 MPa, bending strength of glazed body 230 MPa, dielectric strength 32 kV/mm, thermal shock resistance 200 K.
