Sb-CONTAINING MATERIAL, ITS PRODUCING METHOD AND METHOD FOR SUPPRESSING EXCESSIVE Sb CONTENT OF Sb-CONTAINING MATERIAL

摘要

PROBLEM TO BE SOLVED: To make the Sb content in an Sb-containing material close to the theoretical value shown in the chemical composition. SOLUTION: Sb-excessive powder and Sb-deficient powder are mixed in a prescribed ratio, and sintering is performed to suppress the excessive Sb content to the Sb content as the theoretical value from the chemical composition of the Sb-containing material.
