摘　　要：以硅酸钠和硫酸为原料,采用沉淀法制备二氧化硅微粉;用玛瑙罐球磨石英砂制备二氧化硅微粉.通过SEM、XRD、TGA考察了这两种方法制备二氧化硅微粉的区别.Fine silica powders were prepaired by controlled hydrolysis of sodium silicate in vitriol solution and by grinding quarty sand in an agate pot respectively. The difference between silica particles, made by these two methods is characterized through SEM, XRD and DTA.
