RECOVERY OF INDIUM FROM In2O3 AND LIQUID CRYSTAL DISPLAY POWDER USING DEHYDROCHLORINATION OF POLY (VINYL CHLORIDE)

摘要：

Indium (In) was found to be recovered from In2O3 and LCD powder using poly (vinyl chloride) (PVC) as chlorination agent by chloride volatilization process. For In2O3, the degree of In recovery increased with increasing the molar ratio of Cl in PVC to In in In2O3 (Cl/In molar ratio) under the flow of N2 and air. Particularly, the degree of In recovery increased notably with increasing temperature under the flow of N2. The degree of In recovery from Liquid Crystal Display powder was lower than that from In2O3.
