It was established that the using of alumina A 16 SG and A 1000 SG brands in combination with dispersing additives, in particular with a carboxylic acid based additive, for production by slip casting into gypsum molds of qualitative highrefractory corundum highdensity ceramics with Al2O3 content — not less than 99.5 %, Fe2O3 — not more than 0.05 %, MgO — no more than 0.25 % and open porosity not more than 0.8 % after firing at 1580 °C are suitable.
