Abstract
Disclosed are a czochralski apparatus for growing crystals and a purification method of waste salts using the same. More particularly, the present invention provides a czochralski apparatus for growing crystals comprising screw thread for fixing salt crystals mounted on a pulling bar of the apparatus in order to prevent desorption of crystals caused by load thereof during a crystal growing process without requiring alternative seed crystals and, in addition, a method for purification of waste salts, which can isolate impurities from molten waste salts using a czochralski crystal growing process without alternative adsorption medium, does not generate secondary wastes and may continuously purify the waste salts.
