CALCIUM-DEFICIT CALCIUM-SILICON COMPOUND AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a calcium-deficit calcium-silicon compound including scarce impurities and a method for manufacturing the same.SOLUTION: The provided calcium-deficit calcium-silicon compound is obtained by heating CaSiand then reacting the CaSiwith a halogen-containing gas so as to withdraw Ca from the CaSiand to generate CaSi(0
