Used in dust control on roads and construction sites by suppressing airborne particles due to its hygroscopic nature. Commonly applied in soil stabilization and road base maintenance to improve structural integrity. Employed in concrete acceleration as an admixture to promote faster setting in cold weather. Utilized in industrial processes for wastewater treatment and as a precursor in the production of magnesium metal and refractory materials. Also used in agriculture as a source of magnesium for plant nutrition, especially in magnesium-deficient soils. In food processing, it serves as a coagulant in tofu production. Additionally, used in medical applications as a source of magnesium ions for electrolyte replenishment in some formulations.
