1. Light calcium carbonate can be used as leavening agent, flour treating agent, anti-coagulation agent, acidity regulator, nutrient strengthening agent, curing agent, etc.

2. Used as feed fortifier.

3. Calcium carbonate whisker is one of the earliest and largest fillers used in the rubber and plastic industries.

4. Compared with general granular calcium carbonate, calcium carbonate whiskers showed significant strengthening and toughening effects.

5. It is the filling material of rubber, which can make the rubber luster bright, the elongation is big, the tensile strength is high, the wear resistance is good.

6. Used as an analytical reagent, as a reference reagent.

7. As a white filler for plastics, paper, rubber, paint, ink, etc., it is one of the most widely used fillers.

8. It is used for making raw materials such as fragrant powder, powder cake, gouache and rouge, etc. It is also used as flavoring mixture when making powder cosmetics, and mainly used as friction agent in toothpaste, which is a hard abrasive for toothpaste.
