Aluminum, dysprosium and boron co-doped zinc oxide varistor and preparation method thereof
The invention provides an aluminum, dysprosium and boron co-doped zinc oxide varistor. The aluminum, dysprosium and boron co-doped zinc oxide varistor is prepared from the following raw materials: 1.0 to 2.0 percent of Bi2O3, 1.0 to 2.0 percent of Sb2O3, 0.5 to 1.0 percent of MnO2, 0.5 to 1.0 percent of NiO, 0.5 to 1.0 percent of Co2O3, 0.1 to 0.5 percent of B2O3, 0.1 to 0.5 percent of Dy2O3, 91.5 to 96.5 percent of ZnO and 0.1 to 0.5 percent of an aluminum source. The invention also provides a preparation method of the zinc oxide varistor. Due to co-doping of aluminum, dysprosium and boron, the zinc oxide varistor provided by the invention has a high gradient voltage up to 500V/m, and has the advantages of low residual voltage, small leakage current, excellent aging performance, good temperature characteristic and the like.
本发明提供了一种铝、镝、硼共掺杂的氧化锌压敏电阻，由以下原料制备得到：Bi2O31.0～2.0％，Sb2O31.0～2.0％，MnO20.5～1.0％，NiO0.5～1.0％，Co2O30.5～1.0％，B2O30.1～0.5％，Dy2O30.1～0.5％，ZnO91.5～96.5％，铝源0.1～0.5％。本申请还提供了氧化锌压敏电阻的制备方法。本申请提供的氧化锌压敏电阻由于铝、镝和硼的共掺杂，具有可达500V/m的高梯度电压，同时具有低残压、小泄漏电流、老化性能优异和温度特性良好等优点。
