Research Advances in Preparation and Application of Nanoboride

Transition metal boride materials are made in multiple industrial applications due to high hardness, good conductivity and wear resistance. The main preparation process of nano boron, such as heat plasma method, heat reactive method, wet chemistry method, solid phase reactions and pulse discharge method, and the application of boron and boride in electromechanical, metallurgical and light industrial fields, were reviewed. The development trend of boron and boride was prospected.
