Used as a refractory material in furnace linings due to its high thermal stability and resistance to basic slags. Commonly employed in the production of crucibles, kiln components, and industrial furnace bricks. Acts as an electrical insulator in heating elements while efficiently conducting heat. Specifically utilized in the production of fiberglass to enhance mechanical strength, thermal stability, and chemical resistance. Utilized in agriculture to correct magnesium deficiency in soils and reduce soil acidity. Applied in construction as a component in fire-resistant boards and panels. Found in pharmaceuticals as an antacid and dietary magnesium supplement. Also used in wastewater treatment to neutralize acidic effluents and remove impurities.
