[Abstract]:Boron carbide (B _ 4C) is a kind of special ceramics with excellent properties. It has been widely used in military, nuclear industry, aerospace and other fields. In recent years, the preparation of boron carbide ceramics by precursor transformation has made great progress. Compared with other preparation methods of boron carbide materials, the precursor conversion method has the advantages of simple element composition, good formability, high ceramic yield, low energy consumption, etc., in the preparation of boron carbide powder, fibers, mesoporous materials, etc. Microspheres are widely used in many fields. In this paper, the latest research progress in the preparation of boron carbide ceramics by precursor transformation is reviewed. The synthesis and application of boron carbide precursor are emphatically introduced, and the development direction and application prospect of boron carbide ceramics prepared by precursor transformation method are prospected.
