An impermeable ceramic mold is disposed within a steel die and used in a process for pressure casting of elevated melting temperature alloys and pressure infiltration casting of elevated melting temperature alloys having wear resistant particles, included therewith. The ceramic mold provides an insulation layer between the molten metal and the steel die, and prevents welding between the molten metal and the die. The alloy steel die encloses the ceramic mold and provides the strength needed to resist the pressures generated during pressure infiltration casting.
