摘　　要：本文首次用共沉淀法获得了Ｓｂ２Ｏ３－Ａｌ（ＯＨ）３的超细粉末、比表面达６９ｍ２／ｇ，换算粒径为０．０２３μｍ。粉末Ｓ－Ｒ的衍射结果表明，所制备的样品中Ｓｂ２Ｏ３以斜方晶型存在，Ａｌ（ＯＨ）３以无定型结构存在。研究了温度、洗涤方法、ｐＨ值等因素对比表面及产率的影响。The ultrafines of Sb2O3-Al(OH)3 were obtained for the first time by coprecipitation method. Its specific surface reaches 69m2/g, in this case, the particle size is equal to 0.023μm in diameter.The pattern of X-ray powder diffraction shows that the structure of Sb2O3 and Al(OH)3 is crystalline and amorphous,respectively.The effects of several conditions, such as temperature,washing method, d/D values,pH,on the specific surface and yield were studied.
