Bauxite, as a high-quality high-temperature insulation material, is widely used in metallurgy, ceramics, construction and other fields due to its excellent high-temperature resistance and thermal insulation effect. It not only improves the safety of industrial production, but also contributes to energy conservation and environmental protection. With the promotion of scientific and technological development, the application potential of bauxite will continue to expand in the future, further supporting the sustainable development of industry.
