Abstract

1500414 Electric resistance heating XEROX CORP 14 April 1975 [26 April 1974] 15230/75 Heading H5H [Also in Division F4] An open boat crucible 10, particularly for vacuum deposition, has its bottom surface provided with a thin layer of gold 23 having a thickness of at least 600 Angstrom units, said layer of gold serving to reduce by reflection the infra-red radiation emitted through the back of the crucible. The main body 20 of the crucible, which is formed with a shallow cavity 11 for holding an evaporative charge, is made of tantalum, molybdenum, columbium or stainless steel, the cavity being coated with a layer of SiO. As shown, the bottom surface of the crucible is first coated with a layer 22 of potassium silicate and then overcoated with a layer 23 of gold applied by electro- or vacuum deposition. To assist adhesion of the gold, a thin chromium layer may be applied to the potassium silicate coating prior to the deposition of the gold, the maximum thickness of the chromium layer being 200 Š. The crucible has end plates 13 and 14 provided with slots 15 adapted to be connected to a source of electrical power for resistance heating and/or for bolting a plurality of crucibles together (see Fig. 2, not shown).
