Metal Oxide ZnO-Based Varistor Ceramics [PDF]
, 2011 A varistor is a type of resistor with a significantly non-ohmic current-voltage characteristic. The name is a portmanteau of variable resistor, which is misleading since it is not continuously user-variable like a potentiometer or rheostat and is capacitor rather than resistor at low field. The most famous type of varistor is metal oxide varistor (MOV),

Gaoya dianqi, 2023 金属氧化物压敏电阻（metal oxide varistor,MOV）广泛应用于各种直流断路器中，用于抑制过电压、系统能量耗散与开断电压建立。受目前加工工艺限制，单MOV阀片通流能力有限，故断路器中多采用多柱并联结构。柱间电流分配不均会导致局部阀片超负荷耗能，造成开断失败甚至设备损坏。文中基于实验测量建立了一种直流开断工况下的MOV电气模型，基于该模型提出了MOV阀片均流选配方法。经实验验证，传统基于雷电冲击测试方法选配的MOV在直流开断工况的均流特性不能完全满足要求 ...

Recovery of Antimony: A Laboratory Study on the Thermal Decomposition and Carbothermal Reduction of Sb(III), Bi(III), Zn(II) Oxides, and Antimony Compounds from Metal Oxide Varistors [PDF]
, 2018 As antimony is typically present in industrial and commercial products only in small amounts, the concentration of antimony in waste types is low and a limited amount of antimony is currently recycled. One product relatively rich in antimony is the metal
