摘要： A method and apparatus for the preparation of single crystals of group II-VI compounds such as ZnSe and CdTe and group III-V compounds such as InP and GaP or of ternary compounds thereof, from which some of their components are likely to be dissociated and evaporated during crystal growth at high temperatures. Single crystals are prepared which enable the preparation of high quality compound single crystals and prevent the contamination of furnace structures. The method includes melting a source material in a container by heating in a furnace body and solidifying the melt by cooling from the bottom to grow a single crystal. The container is enclosed by an airtight chamber communicating to the outside with a pressure equalizing passage. Heating is performed while the passage is held at a low temperature equal to or lower than the melting point of a high-dissociation-pressure component of the source material. The apparatus includes a container for holding the source material, a hermetical furnace body including a heater to heat the container, an airtight chamber inside the heater which encloses the container and a pressure equalizing passage communicating with the airtight chamber and forming a lower portion of the chamber.

摘要： A process for preparation of capsule for use in isostatic pressing treatment, the process comprising a first step of enclosing a material to be treated, such as ceramic, metal, resin, etc. with metallic foil having a thickness of from 30 to 300 .mu.m, and a second step of welding the metallic foil so as to seal the material to be treated in the metallic foil thus welded, thereby preparing a capsule, wherein the welding is carried out by means of TIG welding. Alternatively, the welding may be carried out by means of seam resistance welding. It is posible, by the process, to seal the material to be treated in a capsule easily and economically. The capsule thus obtained is in a good sealed condition, permits effective isostatic pressing treatment, and enables the treated material to be taken out easily. A ceramic or metal layer covers the material to be treated to prevent adhesion between the material and the metallic foil.
