Industry
Magnesium sulfate, along with other compounds such as potassium and calcium salts, amino acids, silicates, and other minerals, finds extensive use in various industrial applications. These include:
Tanning: Magnesium sulfate is used to treat leather, helping to improve its quality and durability.
Paper: It is used in the paper manufacturing process to enhance the brightness and strength of paper.
Porcelain: Magnesium sulfate contributes to the production of high-quality porcelain by improving its texture and finish.
Printing and Dyeing: It is used in the textile industry to fix dyes and improve colorfastness.
Lead-Acid Batteries: Magnesium sulfate can be used in the production and maintenance of lead-acid batteries to optimize performance and longevity.
Building Materials
When dissolved in water, magnesium sulfate can react with light-burning magnesia to form magnesium oxysulfate cement. Magnesium oxysulfate cement possesses excellent fire resistance, thermal insulation, durability, and environmental friendliness. It is widely used in applications such as fire door core panels, wall insulation boards, silicon-modified insulation boards, and fire-resistant boards.
