ZnO-Co3O4-Cr2O3-La2O3 세라믹스의 결함과 입계 특성에 미치는 CaCO3의 영향

Liquid phases in ZnO varistors cause more complex phase development and microstructure, which makes the control of electrical properties and reliability more difficult. Therefore, we have investigated 2 mol% $CaCO_3$ doped $ZnO-Co_3O_4-Cr_2O_3-La_2O_3$ (ZCCLCa) bulk ceramics as one of the compos...
