Titanium diboride （TiB2） has attracted great interest for its good comprehensive properties, such as high melting point, high hardness, high thermal stability and excellent resistance to oxidation. As an excellent hard phase, TiB2 is recognized as a Hi-tech Materials in the field of composite material and cermet. In the present paper, the research and development achievements of TiB2 based cermet and TiB2 based composite material in recent years are introduced emphatically, and the research development directions are summarized in special, which include （1） selecting suitable composite materials, （2） exploring suitable composition technology, （3） finding out suitable intermediate composites, （4） developing suitable bonding agents with excellent cohesiveness, （5） decreasing productive cost further. In addition, it is believing that the application fields of TiB2 are becoming more and more widespread as the designing of new materials and the development of preparative technique.
