FIELD: foundry. SUBSTANCE: method consists in that calcined mold is coated by rinsing with protective coating of the following composition, mas. % : powder of molten yttrium oxide with grains sizing within 50 microns 30-43; aluminium powder with grains within 40 microns 0.5-2; yttrium nitrate hexahydrate 20-25; commercial ethyl alcohol 25-40; the balance, water. After drying, the mold is repeatedly calcined at 1200-1500 C for 2-8 h. EFFECT: improved casting quality due to higher thermodynamic stability of mold. 2 cl
