Used as a dust suppressant on roads and construction sites due to its hygroscopic nature, which helps retain moisture and reduce airborne particles. Commonly applied in soil stabilization and road base construction to improve compaction and reduce erosion. Employed in the production of magnesium oxide cement for fire-resistant building materials. Utilized in agriculture as a source of magnesium for plant nutrition, especially in magnesium-deficient soils. Found in some food processing applications, such as a coagulant in tofu production. Used in pharmaceuticals and cosmetics for magnesium supplementation and as a stabilizing agent in certain formulations. Also serves as a de-icing agent on roads and walkways, less corrosive than sodium chloride.
