Ultra-high temperature ceramics (UHTC) such as ZrB₂, ZrC, HfB₂, HfC and TaC have been recently investigated for the application to hyper-sonic systems such as nose-cone, rocket nozzle and leading edge. In this paper, the recent research results about UHTC have been reviewed. Domestic and international research results about UHTC mainly during the last 5 years were briefly summarized. Also, the results of C³HARME project, which was one of the Horizon 2020 program in EU, to get over the problems of UHTC such as brittleness through the fabrication of ultra-high temperature ceramic matrix composites (UHTCMC) were briefly introduced.
