Industrial salt/rough salt has a wide range of applications in the industry and is one of the basic raw materials in the chemical industry, known as the "Mother of Chemical Industry." Most of the main products in the basic chemical industry, such as hydrochloric acid, caustic soda, soda ash, and ammonium chloride, are produced using industrial salt as the raw material.

Material: The industrial salt from Shandong originates from the underground brine of the south shore of Laizhou Bay. The unique brine resources contribute to the superior quality of the product.

Particle Size: Greater than 10mm

Color: White or light gray

Molecular Weight: 58.5

Specific Gravity: 2.1—2.3 g/cm³

Specific Gravity: 0.7—1.5 g/cm³

Melting Point: 800-903°C

Boiling Point: 1439°C

Specific Heat: 0.207 kcal/kg·°C (average value from 0 to 100°C)

Electrolytic heat: -1.281 kcal/mol (dissolved in 200 mol of water)

Solubility: Easily soluble in water

Hygroscopicity: Sodium chloride itself is not hygroscopic, but magnesium salts within it have strong hygroscopic properties. Therefore, when the raw salt contains mother liquor or a high magnesium chloride content, it is prone to caking.
