Zirconium boride is one of the most important ultrahigh temperature ceramics(UHTCs), which are urgently required for the development of the aerospace,advanced weapons,and energy. In this paper the reasons for excellent function of zirconium boride are discussed,and the progress of preparation of zirconium boride is reviewed. The mechanisms of preparation processes of zirconium boride,such as soild-phase methods,vapor-phase methods,and precursor methods are introduced. Their advantages and disadvantages are compared. Accordingly,polymer-derived ceramic is an ideal processy for preparing zirconium boride ultrahigh temperature ceramic matrix composites for its easy design,high purity,controllable molding and low transform temperature. So the study on polymer precursor of zirconium boride ceramics would be one of the most important directions of development.
