摘　　要：鉴于气氛炉设备昂贵,笔者提出用非气氛炉烧结SrTiO3基环形压敏电阻器.并研制了与之相匹配的SrTiO3基环形压敏电阻器双功能(电容–压敏)瓷料.采用电子陶瓷常规设备(箱式炉或隧道炉)与工艺技术,制备了电性能符合标准要求的SrTiO3基环形压敏电阻器产品:V10mA=3.0~30.0 V,α= 3~9,C = 15.0~140 nF.结果表明:非气氛炉烧结技术,具有成本低、易操作、效率高的优点.The SrTiO3-based double function (capacitor-varistor) ceramics materials were prepared by conventional electronic ceramic equipments and productive technology. The electrical properties of obtained ring varistor accord with practical indexes, V10mA=3.0~30.0 V, α = 3~9, C = 15.0~140 nF. The non-atmosphere oven sintering technology has following advantages: low cost, easier operation and high efficiency.
