SINTERED COMPACT OF INTERMETALLIC COMPOUND COMPOSED OF MAGNESIUM, SILICON AND TIN, AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To easily produce the single phase sintered compact with excellent performance characteristics of an intermetallic compound composed of the metals of Mg, Sn and Si expressed by chemical formula: Mg2Si0.50Sn0.50. SOLUTION: A mixture obtained by mixing Si powder with Sb or Bi powder as a dopant, Mg and Si are brought into solid-liquid reaction so as to synthesize a solid solution, and thereafter, the powder of the solid solution is hot-pressed so as to obtain the objective sintered compact. Thus, the single phase sintered compound whose Seebeck coefficientαand specific resistanceρcan be controlled by the control of carrier concentration n and having excellent thermoelectric performance is produced.
