Zusammenfassung:A possibility to produce high density ceramics from metal-like high-melting compounds, IVa, Va Group transition metal carbides, nitrides, borides, and from non-metal high-melting compounds of B sub 4 C, SiC, Si sub 3 N sub 4 , AlN without use of activating additions has been investigated. Ceramics have been sintered at pressures up to 7.5 GPa and temperatures up to 2200 deg C. Optimal sintering regimes, and physicomechanical and thermophysical properties of the produced ceramics have been determined.
