Supporting member for quartz crucible
专利汇可以提供Supporting member for quartz crucible专利检索，专利查询，专利分析的服务。并且PURPOSE:A supporting member for a quartz crucible, prepared by engaging divided graphite frames with a graphite receiving holder supporting the frames with many heat-resistant rotating bodies, scarcely damaging the graphite frames, and reusable repeatedly many times. CONSTITUTION:A graphite frame 1 is assembled to form a crucible from three divided bodies (1a), (1b) and (1c), and many carbon balls 3,... having almost the recess in the top central part of the graphite receiving holder 2. A quartz crucible is engaged with the interior of the graphite frame 1, and a rotating shaft is engaged with the bottom recess of the receiving holder 2 to support the resultant supporting member for the quartz crucible and the quartz crucible rotatably in a chamber. A silicon raw material is then introduced into the quartz crucible and molten, and a seed crystal is then dipped in the molten silicon. The seed crystal is pulled up while rotating the seed crystal and the rotating body in the opposite direction. After pulling up a single crystal silicon ingot of a given length, the interior of the chamber is cooled. The above-mentioned procedures are repeated to prepare the aimed single crystal ingot.，下面是Supporting member for quartz crucible专利的具体信息内容。
