A METHOD OF PREPARING TITANIUM SUBOXIDES USING MOLTEN SALT ELECTROLYSIS

摘要

PURPOSE: A preparing method of a titanium suboxide using the electrolytic reduction of molten salt is provided to selectively produce various kinds of titanium suboxide by the reaction time, using the electrolytic reduction of molten salt. CONSTITUTION: A preparing method of a titanium suboxide marked with chemical formula 1: TinO2n-1, comprises a step of performing the electrolytic reduction of titanium dioxide inside the molten salt of calcium chloride. In the chemical formula 1, n is a fixed number of 2~4. The electrolytic reduction process is performed by an electrolytic reduction apparatus including a positive electrode and a negative electrode containing the titanium dioxide. The electrolytic reduction process is proceeded at 700~1,000 deg C for 20~400 minutes.
