Abstract:
Slurry which contains a) from (50) to (80)% by weight of refractory particles having an average particle size of from (0.5) m to (150) m, b) from (5) to (35)% by weight of aluminum oxide particles having an average particle diameter of less than (300) nm and c) from (5) to (35)% by weight of water and d) a pH of from (5) to (12). Process for producing the slurry using a dispersion, and also the dispersion itself. Process for producing a casting mold, and also the casting mold itself.
