摘要
Abstract
Several carbon/boron thermal reduction methods for the preparation of ZrB2 were briefly compared,in which,the B4C reduction method was simple,low cost,and easy to remove impurities.It can be easier to prepare pure ZrB2.The effects of different reaction molar ratios and different synthesis temperatures on the purity of ZrB2 were studied based on the B4C reduction method.The results indicate that,when the reaction molar ratio of B4C to ZrO2 is 0.77 and the synthesis temperature is 1700 ℃,the pure ZrB2 with almost no ZrO2 and B2O3 impurity can be obtained.Finally,the effect of different reaction molar ratios of ZrB2 on the high temperature conductivity was studied.According to the research,the conductivity increases with the increase of the purity of ZrB2.关键词
