摘要： This invention relates generally to a novel directed metal oxidation process which is utilized to produce self-supporting bodies. In some of the more specific aspects of the invention, a parent metal (e.g., a parent metal vapor) is induced to react with at least one solid oxidant-containing material to result in the directed growth of a reaction product which is formed from a reaction between the parent metal and the solid oxidant-containing material. The inventive process can be utilized to form bodies having substantially homogeneous compositions, graded compositions, and macrocomposite bodies.

摘要： The present invention relates to a high-temperature thermoelectric couple and the method for making the same. The method requires a very small number of fabrication steps. It includes an act of fabricating an n-type leg that, in a stacked configuration, includes a low electrical contact resistance metallization foil that is connected to each of the two sides of Lanthanum Telluride via a thin metallic adhesion layer. Additionally, a p-type leg is fabricated that, in a stacked configuration, includes a low electrical contact resistance metallization foil that is connected to each of the two sides of 14-1-11 Zintl. Finally, CTE-matched, low electrical and thermal resistance plate interconnects are used for each of the two legs to interface with the heat source and heat sink and form an electrical connection.
