【Abstract】 The paper studies the technical conditions for preparing zinc borate with orthogonal test. The conditions are: temperature of 296 K, ratio of quantity of matter of ZnSO 4·7H 2O to Na 2B 4O 7·10H 2O as 1.05∶1, ratio of mass of liquid to solid as 4.5∶1, reaction time of 4.5 h. The product prepared under these conditions is characterized.更多还原
