Verification and determination of the halogen organic combination reaction.Water analysis.Verification of phosphorus.Decomposition of silicate with ammonium chloride.Preparation of calcium chloride solution with standardized soap.Manufacturing optical neodymium glass raw materials, coating materials. Other USES

Can be used as additive in food industry.

They can be used for construction and paper industry.

Less than 200 mesh: can be used for all kinds of feed additive quantity reach more than 55.6 without harmful ingredients.

250 mesh to 300 mesh, used for plastics, rubber factory, paint factory, the factory of the raw materials and external painting.Whiteness is more than 85 degrees.

350 mesh to 400 mesh: used in the manufacture of gusset plate, water pipe, chemical industry.Whiteness is more than 93 degrees.

400 mesh to 600 mesh: paste can be used in toothpaste, soap.Whiteness is more than 94 degrees

800 mesh: used in rubber, plastic, cable, PVC white degree above 94 degrees

1250 mesh, PVC, PE, paint, coating products, paper coating, paper surface coating, white degree above 95 degrees.High purity, high whiteness, non-toxic, odourless, low oil, low hardness.

Calcium carbonate as a calcium supplement: absorption rate can reach 39%, second only to a calcium acid soluble in acid, has become the most formulations, application the most calcium supplement.
