【Abstract】 A ZnO based semi conductive compound can be got by mixturing ZnO powder with many metal oxide additives, and then sintering at high temperature, grinding and screening. The effect of semi conductive degree for the ZnO semi conductive compound and additives on resistivity have been studied by V I properties measurement The experimental results show that the ZnO semi conductive compound can be used as additives for corona-proof semi conductive coating for conducting bar of large motor更多还原
