Barium sulphate is the inorganic compound with the chemical formula BaSO4. It is a white crystalline solid that is odorless and insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. The white opaque appearance and its high density are exploited in its main applications.
Uses :
Hardness control is a highly soluble, dry powder product used for the reduction of hardness in boilers. It will precipitate calcium hardness as a non-adherent sludge.
Hardness control transforms scaling salts like carbons, sulphates, and calcium or magnesium chlorides in phosphates that do not adhere to the exchange surfaces and are easily blowed down. It is used in conjunction with alkalinity control for the prevention of scale and corrosion in low and high-pressure boiler systems.
Activated alumina ball is a white sphere, insoluble in water and organic solvent, soluble in strong acidic and alkaline solutions, moisture adsorptive in air, not expanding and cracking after adsorbing water. Activated alumina ball has the characters of high strength, resistance to sulfate poisoning and good thermal stability.
