Barite is an important non-metallic mineral raw material, which has a wide range of industrial applications, especially in the field of chemical production. The main component of barite is barium sulfate (BaSO4), and its unique chemical and physical properties make it play a key role in many chemical processes. The following are the upstream and downstream related products of barite in the field of raw materials for chemical production.

1. Upstream product

(1) Sulfuric acid: Sulfuric acid is one of the main raw materials for the production of barite, which is used to react with barium salt to form barium sulfate.

(2) barium salt: barium salt, such as barium carbonate, barium nitrate, etc., can react with sulfuric acid to generate barite.

(3) natural barite ore: natural barite ore after crushing, grinding, purification and other processes, chemical grade barite products can be obtained.

2. Downstream product

(1) Plastic filler: Barite can be used as a plastic filler to improve the hardness, wear resistance and dimensional stability of the plastic. Common applications include plastic products such as polyethylene and polypropylene.

(2) Paints and coatings: Barite has excellent whiteness and hiding power, and can be used as a pigment in paints and coatings to improve the hiding power and weather resistance of coatings.

(3) Rubber products: Barite can be used as a reinforcing agent for rubber products to improve the hardness and wear resistance of rubber. Common applications include tires, tapes, etc.

(4) Ceramic products: Barite can be used as ceramic raw materials for the production of ceramic products, such as ceramic tiles, sanitary ware, etc.

(5) Glass products: Barite can be used as a glass additive to improve the refractive index and stability of the glass.

(6) printing ink: barite can be used as pigment of printing ink to improve the hiding power and printing effect of ink.

In short, barite has a wide range of upstream and downstream related products in the field of chemical production raw materials, which plays an important role in promoting the development of the chemical industry.
