The slag-resistant highly-refractory alumina-periclase carbonaceous ceramic materials were synthesized out of the Kazogneupor's electro-cast corundum, Zinel'bulaksk's (Uzbekistan) talc, and enriched graphite concentrate (Uzbekistan). The crystal structure of the materials is formed of corundum and spinel. The refractoriness of the ceramic samples is higher than 1800 °C, the density is 2520‒2880 kg/m 3 , the water absorption is 6,75‒11.71 %, open porosity is 16‒21 %, and the ultimate compression strength is 100‒120 MPa.Ill. 3.
