    Ultra-high temperature ceramics are a new type of heat-resistant materials that could withstand extreme service environments such as long periods of ultra-high sound speeds, atmospheric flight, and re-entry. It usually refers to advanced ceramics with a melting point above 3 000 ℃ and the ability to resist ablation in an oxidizing atmosphere above 2 000 ℃, mainly including carbides,nitrides, and borides of transition metals in the IVB and VB groups. As thermal protection materials used in extreme environments, single-phase ultra-high temperature ceramics exhibit extremely poor antioxidant performance in extreme environments. In this paper,the development of ultra-high temperature ceramics is moved towards diversification and multiphase, and ultra-high temperature ceramic matrix composites are formed by compounding with fibers and other materials.Polymer conversion methods mainly include two types: the first type is metal hybrid polymer method, which use alcohol oxides(such as alcohol organic compounds, acetate, acetylacetone, salicylic acid, etc.) to modify and obtain polymer precursors with M (Ti,Zr, Hf, Ta, Nb, etc.) and O acted as the main chains; The second type is the metal organic polymer method, which choose alkyl,alkenyl, alkynyl or aryl ligands to realize the chemically modified organic metal compounds (such as metallocene compounds, methylamine metal compounds, etc.) to obtain polymer precursors containing M and C or B bonds. With the diversification and multiphase development of ultra-high temperature ceramics, the multi-component nanocomposite ceramics obtained by reacting metal with polycarbosilane, polysilazane, polyborosilicate, etc. were significantly better than those obtained by traditional ultra-high temperature ceramics. The polymer conversion ultra-high temperature ceramic technology could realize the control of the composition, microstructure, properties, etc., which could exhibit a revolutionary significance in the preparation of structure function integrated ceramics.
