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 heat-resistant bricks and crucibles. Acts as an electrical insulator in heating elements while efficiently conducting heat. Widely used in agriculture and feed industries to correct magnesium deficiencies in soils and animal diets. Employed in wastewater treatment to neutralize acidic conditions and remove phosphates. Found in pharmaceuticals as an antacid and laxative to relieve indigestion and constipation. Utilized in construction as a component in fireproofing and insulating boards. Also serves as a filler in plastics and rubber to improve thermal performance and flame resistance.
