Abstract：Ultrafine Sb2O3 powders were prepared by wet chemical m ethods，the characteristics of the compos ite powder was studided by TG，DSC，SEM an d laser scattering methods．The TG and DS C showed that compared with ball mill me thod，the lose weight of wet chemical met hod sample was larger than that of the former；the lose weight temperature scope and exothermic peak temperature scope were also wider than that of the ball mill method sample ．The chemical combination reaction activ e energy of the wet chemical method samp le is similar to the ball mill method sa mple．The SEM analysis and laser scatteri ng analysis showed that the main of the composite powder were smaller than 0．20μ m，oblique square shape Sb2O3 were the main composition of the wet chemical met hod sample；kaolin adhered to the surface of the Sb2O3 sample，there were physic al and chemical action between the kaoli n powder and the surface of Sb2O3．Afte r heated treatment for two hours at 600℃ ，the sample powder combine closer．
