Preparation and Application of Al-Si and Al-Si-Fe Alloys from Al-Si Min-erals

A large number of industrial solid waste containing aluminum and gradually depleted high-quality bauxite resources have brought new challenges to the development of the Chinese aluminum industries. In order to reduce the pollution of industrial solid waste containing aluminum on the natural environment and alleviate the current situation that aluminum ores are heavily dependent on imports, the preparation of Al-Si and Al-Si-Fe alloys by carbothermal reduction method of recycling solid waste containing aluminum and low-grade bauxite has attracted wide attention. The application of carbothermal reduction method to prepare Al-Si and Al-Si-Fe alloys is also a hot research topic. This paper reviews the research and industrial status of Al-Si and Al-Si-Fe alloys prepared by carbothermal reduction using low-grade bauxite resources and aluminum-containing solid waste as raw materials at home and abroad, and analyzes in detail the application ways of Al-Si and Al-Si-Fe alloys prepared by carbothermal reduction. According to the latest research progress in preparation of Al-Si and Al-Si-Fe alloys by carbothermal reduction, the prospect of preparation of Al-Si and Al-Si-Fe alloys by carbothermal reduction is prospected.
