摘　　要：以In粒和Sn粒为原料,尿素为燃料,柠檬酸为添加剂,燃烧合成ITO(掺锡氧化铟)粉体,利用粉末X射线衍射、扫描电子显微镜对产品进行表征,并研究柠檬酸(C6H8O7)对燃烧产物的影响。结果表明,以尿素为燃料燃烧合成是制备ITO粉体的有效途径,添加剂柠檬酸能有效抑制粉体的团聚,使颗粒分散性变好,得到颗粒细小均匀的ITO粉体。ITO （Indium tin oxide） powders were prepared by combustion synthesis,using indium grains and tin particles as raw materials ,urea as fuel. The products were characterized by X-ray diffraction and scanning electron microscopy. The effects of additives,citric acid （C6H8O7）,on the combustion products were studied. The results show that combustion synthesis with urea as fuel is an effective way to prepare ITO powders,and the agglomeration of ITO powders can be restrained by using citric acid as additives.
