Widely used in dust control and road stabilization, especially on unpaved roads and construction sites. It helps bind fine particles and reduces airborne dust by retaining moisture. Commonly applied in winter for de-icing and anti-icing due to its ability to lower the freezing point of water, with less environmental impact than some alternatives. Used in concrete as an accelerator to improve setting time and strength development. Employed in the production of magnesium oxide boards for fire-resistant building materials. Applied in agriculture as a source of magnesium and chlorine in fertilizers, especially in magnesium-deficient soils. Utilized in wastewater treatment to enhance phosphorus removal. Found in some medical and pharmaceutical preparations as a magnesium supplement. Also used in food processing, particularly in tofu production as a coagulant.
