Precipitated Barium Sulphate
The white precipitate generated by the reaction of barium ions and sulfate ions in the solution is stable in nature and almost insoluble in water, ethanol and acid, but soluble in hot sulfuric acid. Related information: The appearance of precipitated barium sulfate is a white amorphous powder, with a relative density of 4.50 (15 ℃) and a melting point of 1580 ℃. Due to its high refractive index (1.63~1.65), it appears whiter in color and has a certain covering power. It is almost insoluble in water, ethanol and acid, but soluble in hot sulfuric acid.

Our barium sulfate is used in construction, food, pharmaceutical, PVC, personal care and other industries as follows：
1.Pharmaceutical field:
As a contrast agent for X-ray and CT scanning, it can enhance the contrast effect of organs or blood vessels in the body due to its high density and high absorption, helping doctors to make accurate diagnosis.
Used in the treatment of gastrointestinal disorders, such as gastric ulcers and colitis, patients can drink a solution containing barium sulfate and observe the gastrointestinal tract through X-ray examination.
2.Industrial field:
Plastic and rubber: as filler to improve the hardness, abrasion resistance and aging resistance of the products, and at the same time reduce the cost.
Coatings and paints: as white pigment and filler, to increase the thickness, strength and durability of the paint film, and to improve the covering power and gloss of the coating.
Paper making: as filler, improve the whiteness and opacity of paper, improve the smoothness and uniformity of paper.
Ceramics and glass: as raw material to improve the physical properties of products, such as whiteness, density and heat resistance.
Oil and gas: as an aggravating agent for drilling mud to help stabilize well walls and prevent blowouts.
3.Environmental protection:
Used as a precipitant to treat heavy metal ions in wastewater to form water-insoluble precipitates, thus removing heavy metal pollutants.
4.Geological exploration:
As a heavy sand mineral of barite, it is used to measure the grade and reserves of the ore and guide the mining and utilization of the ore.
5.Other fields:
Construction materials: used as concrete aggregate, paving materials, used as shielding material instead of lead sheet in nuclear facilities, X-ray laboratories, etc.
Electronics and optics: used in the manufacture of optical components and window materials due to its high refractive index and optical stability.
