Title: Manufacture of bismuth oxide superconducting wire rod
Inventor: SATO KENICHI
IPC: B21F19/00
Filed: 1991-01-19
Abstract: PURPOSE:To provide a bismuth oxide superconducting wire having high critical current density. CONSTITUTION:Powder of 1mum or less in an average particle diameter, in which a superconductive phase mainly composed of the 2212 phase of Bi-Sr-Ca-Cu or (Bi,Pb)-Sy-Ca-Cu obtained by applying at least one time of calcination and pulverization to raw material powder and a non-superconductive phase are mixed, is prepared. After heat-treating the resultant powder at a high temperature, it is coated with a metal to produce a round wire by plastic working. Subsequently a tape-like or a flat square type wire is produced by plastic working. Next, a heat-treatment is applied under such a condition that a major super conductive phase, namely the 2212 phase, a phase-transforms so that the superconductive phase is composed of 2223 phase so as to grow its grains. Then, the generated 2223 phase is densified by plastic working or a pressing treatment, and heat-treated again so as to strongly bind the 2223 phase and finely disperse the non-superconductive phase.

Title: Manufacturing method of thermoelectric material
Inventor: KAGAWA SHUZO
IPC: H01L35/34
Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To reduce a thermal conductivity and hence increase a thermoelectric performance figure by hot pressing a thermoelectric material within a predetermined time at a temperature where crystallization is achieved, and forcedly cooling a sintered product up to at least a temperature where the crystallization is not promoted. SOLUTION: A thermoelectric material is sintered at a crystallizable temperature with a hot press within a short time of 3 minutes or shorter to form a sintered product, and just after the pressing the sintered product is forcedly cooled up to at least a temperature where crystallization is not promoted. More specifically, just after the pressing, the sintered product is taken out from a metal mold and is forcedly cooled with a fan for example. Hereby, crystal grain of the sintered product is reduced. As a result, a thermoelectric element material having a large performance figure is ensured. Further, a homogeneous thermoelectric element material having substantially no directional property of the crystal is ensured and hence in a molding process there is no need of putting the direction of a dice in order and there is improved a working efficiency in an assembling process.
