Anhydrous sodium sulfate
Product Description:
Anhydrous sodium sulfate
Sodium sulfate is a sulfate chemical substance. It is usually a colorless, transparent or white powder, hygroscopic, commonly known as Glauber's salt, is an inorganic compound, a type of inorganic salt with chemical properties very similar to table salt. It is soluble in water, with most solutions being neutral, soluble in glycerol but insoluble in ethanol. High-purity, fine-particle anhydrous sodium sulfate is called Glauber's salt, and this substance can be used both in medicine and in industrial production.
Sodium sulfate (also known as refined sodium sulfate) is an important raw material for light industry and chemical industry, and is widely used in more than 20 industries such as chemical, light industry, textile, building materials, medicine, fertilizer, and synthetic fiber.
