Abstract
The present invention relates to chemical material, and is the preparation process of superfine high whiteness quartz powder. The preparation process includes the steps of: depurating quartz mineral; crushing and grinding in a SW-3000 wet grinding instrument for 1-1.5 hr while adding sodium dodecyl benzene sulfonate as surface modifier; filtering in a press filter; and drying and grading the filter cake in a XQ-4 powerful drying equipment at inlet temperature of 270 deg.c and outlet temperature of 160-180 deg.c to obtain the product powder with water content less than 1 %, size of 6000 mesh and whiteness of 97 %. The product may be used to replace expensive titanium dioxide powder as excellent stuffing for point, rubber and plastic and has also wide application in electronic and ceramic fields.
