Dependence of residual voltage ratio behavior of SnO_2-based varistors on Nb_2O_5 addition
《Science China(Technological Sciences)》2011年第6期1415-1418,共4页WEI QiaoYuan HE JinLiang HU Jun 
supported by the National Natural Science Foundations of China (Grants Nos 50425721 and 50737001)
SnO2-based varistor samples doped with Co2O3,Nb2O5 and Cr2O3 were prepared by ball-mixed oxide method.The microstructure,nonlinear I-V characteristic and surge current performances of these samples were investigated.T...
