<p>An inexpensive recharge pipe for solid multicrystal material that is capable of improving productivity of single crystal; and a single crystal producing method using the same. The recharge pipe, which is removably installed in the single crystal producing device having a crucible containing a crystal molten liquid, is internally provided with a substantially cylindrical recharge pipe main body for holding a solid multicrystal material therein, the recharge pipe main body gradually widening toward the lower end. The recharge pipe is further equipped with a conical valve removably disposed at the lower end of the recharge pipe main body, a lid removably disposed at the upper end of the recharge pipe main body, a hook, a recharge pipe wire connecting the hook and the conical valve, and a stop for positioning the recharge pipe wire such that is extends through substantially the center of the recharge pipe main body.</p> |
