<p>PURPOSE: A thermoelectric material is provided to selectively precipitate high conductive crystals or magnetism crystals which are composed of transition elements from amorphous materials by microwave heating. CONSTITUTION: A thermoelectric material is semiconducting glass which contains vanadium and at least a part of the materials is crystallized. MxV2O5 crystal is precipitated in the semiconducting glass. In the crystal, M indicates one of metal elements from iron, antimony, bismuth, tungsten, molybdenum, manganese, nickel, copper, silver, alkali metal, and alkaline earth metal. More than 10 volume% of the semiconducting glass is crystallized. Intervals between crystals in the semiconducting glass are 10 nano meters or less.</p> |
