Abstract:
Investment casting shells are manufactured by incorporating fumed metal oxide dispersions, or doped fumed metal oxides as a binder into the casting shell. The investment casting shells containing the fumed metal oxides have improved characteristics, such as increased strength and a reduced surface roughness.
