摘　　要：探讨了煅烧对掺锑氧化锡粉体性能的影响。用X射线衍射进行粉体晶粒尺寸和物相检测,表明粉体晶粒随煅烧温度升高而长大,粉体保持了SnO2的四方相结构。透射电镜结果表明颗粒为球形,随温度升高粒度增加。比较Sb2O5和Sb2O3的标准生成自由能,认为较低温度下Sb的掺杂应为Sb5+。The influence of calcination on antimony-doped tin oxide （ATO） powders was studied. The x-ray diffraction was used to characterize the grain size and phases of ATO powders. The results show that the grain size increases with increasing calcination temperature while the powders retain tetragonal futile structure of SnO2. The transmission electron microscopy micrographs show that all particles are in spherical shape and particle size increases with increasing the calcination temperature too. Compared with Sb2O3 , Sb2O5 has the lower standard free energy of formation and therefore Sb in the SnO2 lattice is Sb^5＋.
