Effect of the sintering temperature on the electrical properties of Y–Al‐doped ZnO varistors by Lei Wang, Hang Zhang, Kexin Zhang, Yubo Shen, Limin Qu, Yue Yin, Pengfei Meng, Jingke Guo

“…Through C--V characteristic testing, X‐ray diffraction and energy dispersive X‐ray spectroscopy analysis, it was found that the increase in sintering temperature promoted the formation of interface negative charge and defect reactions by Y3+, increasing Ni and Nd; Al3+ tends to aggregate in the grain area, further increasing Nd; the volatilization of Bi3+ gradually increases, causing a decrease in Ni; the Φb first increases and then decreases with the changes in Ni and Nd, resulting in a U‐shaped variation characteristic of the nonlinear coefficient and leakage current density. …”
