FIELD: technical ceramics and refractory materials, possible use for manufacturing products used in electric engineering, mechanical engineering, chemical, metallurgic and other industrial branches. ^ SUBSTANCE: method for producing ceramic mass includes low-temperature annealing of plasma-chemical powders of metal oxides at temperature of 800-1000°C during 1 hour, mechanical activation by means of grinding during 25-50 hours in ball mill with addition of 0,25-0,5 mass.% sodium chloride in form of water solution as surfactant, mixing of plasma-chemical powders of metal oxides and organic connective - 12-15 weight.% of paraffin, containing 2-3 weight.% of beeswax. Plasma-chemical powders of oxides of aluminum, magnesium, yttrium, calcium, cerium, zirconium dioxide and their mixtures are used. ^ EFFECT: possible production of ceramic mass on basis of ultra-dispersion plasma-chemical powders of metal oxides with reduced content of organic connective and preserved structure of nano-powders with high values of casting capability. ^ 3 ex, 1 tbl |
