Abstract (en)

An expendable salt core (2) is formed into the shape of a water jacket (6) by, e.g., die casting using a salt of bromine and at least one of sodium and potassium, and a salt of carbonic acid and at least one of sodium and potassium. The expendable salt core (2) is formed to contain at least one of potassium and sodium as a cation, and bromine and carbonic acid as anions. For example, the expendable salt core (2) is formed by casting using a melt obtained by melting a salt mixture of sodium bromide and sodium carbonate.
