Abstract (en)

[origin: WO9832557A1] An integral crucible for casting of reactive metals incorporates a graphite sleeve (10) adapted for attachment of an investment pattern (14) over which a laminate of alternating layers of facecoat slurry (20) and ceramic stucco (22) are applied to form an investment shell. The layers of the laminate extend over a mating portion of the sleeve and firing of the shell vaporizes the investment pattern leaving the sleeve and shell an integral crucible
