[0002] Sodium sulfate, also known as Xuanming powder or anhydrous Glauber's salt, is the common name for sodium sulfate and an inorganic compound. It is widely used in various fields, including medicine, chemicals, papermaking, and textiles. In medicine, sodium sulfate acts as a laxative and antidote, showing significant effects in treating constipation and barium poisoning. In the chemical industry, it is a key raw material for the manufacture of chemicals such as sodium sulfide and sodium silicate. The paper industry utilizes its properties as a cooking agent to improve pulp quality. Furthermore, sodium sulfate is used in textiles, glassmaking, and as an auxiliary agent in various industrial processes.

[0003] Sodium sulfate has become an indispensable component of composite materials. Powder fineness and surface properties are key factors affecting the quality of the material. Modification of inorganic mineral powders involves first grinding the powder to a finer consistency and then chemically treating the powder surface.
