Anhydrous Sodium Sulfate is a white crystalline powder or granular substance at room temperature, odorless and readily soluble in water, with its aqueous solution being neutral. As a neutral salt, it exhibits stable chemical properties without oxidizing or reducing capabilities, and can undergo double displacement reactions under certain conditions, such as with barium salts. Its primary applications are as a basic chemical raw material, widely used in the manufacturing of glass, pulp, detergents, and in the textile dyeing and printing industry. It also serves as a water treatment agent, desiccant, and inert filler in chemical synthesis, and acts as an auxiliary raw material in fields such as dyes, pharmaceuticals, and refrigerants.
