AB - The methods of high-pressure sintering (5 GPa) and, for comparison, conventional hot pressing are used for fabricating high-density specimens from SiC, Si3N4, and A1N with the use of activating additives and without them. The high-temperature oxidation is studied by the method of thermogravimetry at 1400°C with a 150-min hold. The introduction of additives in order to activate the sintering increases the resistance of hot-pressed specimens to high-temperature oxidation and does not influence the stability of materials obtained in a high-pressure apparatus. The corrosion resistance of materials sintered under a high pressure turns out to be much higher than that of hot-pressed materials, which is connected with the formation of superfine-grained densely fit oxide films
