Effect of MnO2 doping on nonlinear coefficeint of Zn-Bi-Ti-O varistor ceramics

The work aims the improvement of nonlinear coefficient (α) can achieve by the addition of MnO2. The investigation regarding to the α variation of MnO2 doping on ZnO-Bi2O3-TiO2 system is discussed. The crystalline phases were identified by an XRD (PANalytical (Philips) X’Pert Pro PW3040/60) with CuK...
