Method for producing scandium chloride and method for producing anhydrous scandium chloride

摘要

Problem to be solved: to provide a method of producing scandium chloride capable of reducing impurities to some extent from the scandium oxide containing impurities.Solution: a method for producing scandium chloride from a scandium oxide containing an impurity and leaching a scandium oxide by hydrochloric acid to obtain a leaching solution containing scandium ions and chloride ions The crystallizing step obtained by cooling the pre crystallized solution obtained by using the leaching solution is crystallized to crystallize scandium chloride from the pre crystallization liquid.Diagram
