Hot pressing of commercially available powders is used to prepare dense ceramic based on ZrB2 –SiC with different additives (Si3N4, TiSi2, ZrSi2, MoSi2). The main physicomechanical properties are measured in macro-specimens: ultimate strength in static three-point bending at room temperature 400 – 600 MPa, Vickers microhardness up to 15 GPa, and critical stress intensity factor up to 5.9 MPa·m1/2. Average LTEC, thermal diffusivity, thermal conductivity, and oxidation resistance over a wide temperature range are determined. Altogether the ceramic properties obtained are at the level of published indices.

Notes
Any compounds of boron, zirconium, and hafnium are classified as strategic raw materials, on which there are export-import limitations. According to [10] within Russia currently there is almost complete absence of in-house production of zirconia refractories.
Ceramic machined surface was measured in a TR-200 profilometer according to GOST 2789.
In the course of treatment under vacuum in the initial HP stages boron oxide partly evaporates. The quantitative residue in ceramic was not evaluated in this work.
The temperature of 1400°C for UHTCM is its “boundary temperature”. Above 1400°C there is melting of silicon and marked softening of the glass phase of the composition Zr–B–Si–O at grain boundaries. Achievement of high strength at these temperatures is technically impossible [3], and is currently being studied. For use in hypersonic aircraft it is necessary that UHTCM have an ultimate strength in bending not less than 200 MPa at above 1500°C [3].
