FIELD: technology of silicates; materials technology.
SUBSTANCE: proposed method includes preliminary dry molding of concentrate by pouring dry concentrate into ingot mold, mullitization at temperature of 1100-1300°C and sintering at temperature of 1400-1500°C. Prior to sintering, semi-finished product is subjected to mechanical treatment for obtaining required geometric shape.
EFFECT: possibility of obtaining articles of intricate shape at simplified technology.
