High-alumina bauxite for electric porcelain is an important industrial raw material. It has high aluminum content, excellent insulation performance and high temperature resistance, and plays a key role in the production of electric porcelain. This material not only improves the strength and service life of electric porcelain, but also enhances its thermal shock resistance. With the improvement of its quality requirements, the application and technical trend of high-alumina bauxite will be more extensive in the future, contributing to the sustainable development of society.
