| PURPOSE:Used for refeeding when pulling monocrystalline silicon. |
PURPOSE:Used with quartz feeder when refeeding for monocrystalline silicon pulling. |
PURPOSE:Used to protect graphite electrode of single crystal furnace. |
PURPOSE:Used to measure the distance between the liquid surface and the guiding tube |
PURPOSE:Instead of graphite internal guiding in CZ method, quartz guiding tube has the advantage of high purity and low cost. |
