The technologies of obtaining ceramics by GP method were studied. The basic structural characteristics and the stress-strain state of UHPC were studied. In the industrial production modes for ZrB2-SiC ceramics, the strength level at room temperature and 1800 ° C varied within 380-420 MPa and 216-253 MPa, respectively. The oxidation resistance of zirconium boride composites increased in a range from carbides to silicides. The optimum thickness for using these materials as heat-resistant is 500 microns. . Investigation of the process of erosion of UHTK in the flow of combustion products from a high-temperature plasma burner at a flow temperature of ~ 1600 ° C. Under these conditions at a temperature of 2100 ° C tested UHTK coatings provide an increase in the lifetime of UHTK before the destruction of the surface for at least 20 minutes ( UVTK compounds ZrB2 - 15 MoSi2) and for 12 minutes (UVTK compounds ZrB2 - 3 SiC - 5 WC).
