ABSTRACT:
A method for purifying starting materials for chalcogenide glass is disclosed, which comprises contacting chalcogen starting materials at a high temperature with a metal which is more susceptible to oxidation than the chalcogen starting materials to allow the metal to react with oxygen contained as impurity in the chalcogen starting material to form an oxide of the metal, and then removing the metal and the oxide of the metal from the chalcogen starting materials.
