摘　　要：共沉淀法和溶胶-凝胶自蔓延法制备出ATO导电粉前驱体,在氧气气氛下,利用TG-DSC同步热分析仪对两种方法制备的前驱体进行热分析可知,无论共沉淀法还是溶胶-凝胶自蔓延法,在形成氧化锡锑共晶物时,其共晶过程的分子重组相似;溶胶-凝胶自蔓延法中,自蔓延燃烧过程是存在的;600℃时,共晶过程没有完全,但不能说明ATO导电粉的其他性能与共晶完全的关系。ATO conductive powder precursor were prepared by methods of coprecipitation and sol gel of self-propagating in an oxygen atmosphere.The two type of precursors prepared were conducted thermal analysis by use of TG-DSC thermal analyzer synchronization.Whether coprecipitation or sol-gel method,when the formation of antimony tin oxide eutectic material,the molecular reorganization in the eutectic process was similar.In sol-gel method,the process of self-propagating combustion was existed.The eutectic process was not perfect at 600℃,but it can not explain the other properties of the powder had not fully relation with eutectic.
