    摘要: A process for the high pressure synthesis of InP using an independent temperature control of a three zone furnace incorporating a heat pipe provides a stable temperature profile throughout the synthesis cycle. Internal/external pressure control of the quartz ampoule is maintained by use of a water cooled baffle and a temperature/pressure balancing program. Complete synthesis is achieved in less than five hours.

    摘要: The present invention is a process and apparatus for the synthesis and growth of single crystals of phosphorus compounds starting with the elemental materials in a single furnace without external exposure. The apparatus of the present invention is a crystal growth furnace heated by RF coils. Inside the furnace is a susceptor for holding a crucible. Above the crucible is selectively positioned a phosphorus improved injector. The non-phosphorus materials are placed in the crucible and melted to a desired temperature. The phosphorus material previously placed within the injector is heated by the radiant heat from the crucible to drive the phosphorus vapor into the melt through a tube. This is closely controlled by noting the temperature within the injector and adjusting the height of the injector above the melt to control the temperature within the phosphorus material. After the formation of the stoichiometric melt, the seed is inserted into the melt for crystal growth if so desired. A further improvement to the above apparatus is the use of an improved injector having a cover and a shield thereabout. The injector and cover have a central hole through which the seed is inserted. The injector is moved vertically within the cover to provide the proper temperature therein.

    摘要: A heat pipe ring for use in a crystal growth furnace is ring-shaped with at least one arm thereon and is constructed as one piece. An RF coil for heating a working fluid in said heat pipe is attached about said arm or an electric current can flow from one arm to an oppositely located arm to heat said body. These rings can be stacked and each may have an independently controlled sources of heat. Each heat pipe ring of the present invention has a wall of three layers of refractory material. In the case of working above 1000.degree. C., the working fluid can be lithium and the wall made of a layer of tungsten, a layer of graphite as a spacer, and a layer of silicon carbide. The internal surface on the tungsten layer is knurled to support capillary action. As a result of these features the heat pipe ring is able to survive high temperatures, greater than 1000.degree. C., high pressures, greater than 80 atm, corrosive atmospheres, a high vacuum, and further provides azimuthal symmetry as well as axial temperature gradient profiles when the heat pipes are stacked and independently heated.

    摘要: A method for synthesizing and growing a single crystal of indium phosphide includes vacuum baking and purifying of elemental indium prior to reacting it with red phosphorus within the same apparatus. The steps growth take place in a vertical apparatus by placing the reaction components within a reaction vessel that is sealed under vacuum after the purification and then heated and cooled within predetermined temperature limits to react indium with red phosphorus to synthesize molten indium phosphide and a single crystal of indium phosphide by cooling the molten indium phosphide within a controlled temperature atmosphere. Excess phosphorus is maintained during growth to eliminate the need for encapsulation of the growth melt.

    摘要: A powder-dispensing assembly for use in combination with a fusion-type crystal-growing furnace in which a carrier gas is used for entraining the powder feed constituents for transportation to the crystal-growing zone thereof. The assembly includes a funnel-shaped powder container positioned an outer container and a means selectively movable for feeding the carrier gas to either the powder container to affect powder fall or to the crystal-growing furnace while simultaneously sealing the powder container to prevent powder fall.
