    • Processes for the continuous preparation of single crystals having a predetermined shape and requiring little or no subsequent machining which processes comprise placing a single crystal-forming material in a crucible fitted in its lower portion with a capillary conduit having a length equal to or greater than the retention length of the molten material in the capillary at the selected temperature and pressure, heating the crystal-forming material to a temperature above its melting point, bringing a performed appropriately oriented crystal seed into contact with the pendant drop formed at the lower point of the capillary, and pulling the seed crystal away from the feed material in the crucible so that the amount of crystal-forming material fed per unit of time is at every instant substantially equal to the quantity of material pulled into single crystal form, together with novel apparatus comprising a capillary-containing crucible, heating means, feed means, enclosure, seed-supporting carrier, means for moving and rotating the carrier, and means for controlling the movement of the carrier.
    • 用于连续制备具有预定形状并且几乎不需要后续加工的单晶的方法,该方法包括将单晶形成材料放置在装配在其下部的坩埚中,毛细导管的长度等于或大于 在选择的温度和压力下熔融材料在毛细管中的保留长度,将晶体形成材料加热到高于其熔点的温度,使得所执行的适当取向的晶种与形成在 毛细管,并将晶种从坩埚中的进料中拉出,使得每单位时间供给的结晶形成材料的量基本上等于被拉入单晶形式的材料的数量,以及新颖的装置 包括含毛细管的坩埚,加热装置,进料装置,外壳,种子支撑 载体,用于移动和旋转载体的装置,以及用于控制载体的运动的装置。
