Application
1. Used for flour treatment agent, transport agent, stabilizer, yeast nutrients, mineral nutrition enhancer.

2. Used as nutrient fortifier for feed.
3. It is a filling material for rubber, which can make rubber bright color, high elongation, high tensile strength and good wear resistance.  Also used as artificial leather, wire, PVC, paint, ink and paper industry filler.  When used to produce microporous rubber, it can make it evenly foaming. 
4. Used as an analytical reagent, as a reference reagent.  Emission spectrum analysis of sample flux, volatile additives.  Also used as silicon single crystal slicing glue, thick film capacitive material, optical glass and pharmaceutical industry raw materials. 
5. As a white filler for plastics, paper, rubber, paint, ink, etc., it is one of the most widely used filler 

6. Used for the manufacture of powder, powder, gouache, rouge and other raw materials, powder cosmetics used as a flavor mixing agent, but also mainly used for toothpaste as friction agent, toothpaste is a hard abrasive.
