Used as an insulating material in high-temperature environments due to its excellent thermal stability and electrical resistance. Commonly found in industrial heaters, furnaces, and electrical equipment where heat resistance is critical. Also utilized in cosmetics as a shimmering agent because of its reflective properties. In construction, it serves as a component in fireproofing materials and thermal insulation boards. Its inert nature makes it suitable for use in specialty coatings and polymer fillers to enhance durability and heat resistance.
