Abstract:
A casting core resulting from alkaline earth metal oxide particles having an average particle size of 0.8-4 mm being dispersed in a water-soluble alkali metal salt matrix. The casting core can be efficiently produced using a method of dispersing alkaline earth metal hydroxide particles having favorable disintegration properties and a particle size in the range of 1-5 mm in a molten water-soluble alkali metal salt, converting to alkaline earth metal oxide particles by means of dehydration, and casting in a mold, cooling, and hardening.
