Abstract:

The amount of charge transfer between metal and boron atoms determines the bonding mode, bonding strength and characteristics of chemical bonds in metal borides (MBs). The preparation, crystal structures and applications of MBs have been a hot topic in the field of chemistry and materials. In view of the extensive application prospect and the limited introduction of MBs in inorganic chemistry textbooks at domestic and abroad, in this work, combined with the references and the latest research results, we focus on the structure, properties, preparation and applications of alkali/alkaline earth metal borides, transition metal borides and rare earth metal borides. This work expands the in-depth introduction of MBs in teaching, helps improve students' knowledge horizons, and reflects the role of scientific research in promoting the reform of undergraduate teaching content.

Key words: Metal boride, Structure, Property, Preparation, Application
