IPC: C04B41/50
Filed: 1975-01-28
Abstract: Carbon boats for the evapn. of aluminium, the novelty being that the surface of the boat is partly or completely coated with a protective layer of refractory metals and/or their nitrides. The refractory metals are pref. Ti and/or Zr and/or Hf and/or Ta, whereas the nitrides are pref. those of boron and/or Ti and/or Hf and/or of Ta. The metal layer is pref. applied by flame- or plasma-spraying and the coating is then pref. exposed to N2 or an atmos. contg. N2, at 800-1400 degrees C. and sintered. Alternatively, the metal nitride layer may be obtd. by chemical deposition from the gaseous phase. The boats are used for the evapn. of Al at ca. 1500 degrees C and 10-5 torr in mfg. capacitor-or decorative-foils. Carbon boats are inexpensive but only have a very short life. The coating is impermeable to the molten aluminium and has a similar thermal expansion to the carbon so that thermal stresses are avoided, the overall result being long life.
