Abstract

1,091,627. Crucible furnaces. ELMAT CORPORATION. March 8, 1966 [March 15, 1965], No. 10149/66. Heading F4B. A crucible furnace for producing a single crystal of germanium or silicon comprises a quartz crucible 75 in a graphite holder 77 surrounded by a resistance heating element 103 in a water-jacketed container 57 having a neck portion 59 forming an air lock closed by a clamped top 188 and by a lower window element 155 rotatable either simply free of the air lock or to form the lower element of a double window 151. Member 155 has a groove 159 containing a sealing gasket 165 engaging either a lip 161 on the neck 59 or a lip 163 on the window aperture 152, which latter is also engaged by a rim 171 on an upper window element 157. Window elements 155 and 157 have a centre transparent area of quartz. Neutral gas, e.g. argon, is supplied to both sections of the furnace through valves 71A and 71B and exhausted through lines 73 and 190. A quartz sampling tube 177 with compressible bulb 179 may be lowered into the melt through a sealing bushing 189 in the top 188. For charging purposes, tube 177 may be replaced by a stainless steel tube (191) having a central rod (192) biased by spring (195) and terminating in fingers (194) grasping a piece of charge material, Fig. 5 (not shown). Thereafter, the tube is replaced by the conventional seed rod.
