Publication number: 20020053662Abstract: Improved Hg-containing superconducting films and thermoelectric materials are provided. The films are fabricated by annealing starting Tl-containing films (e.g., Tl-1212 or Tl-2212) in an Hg-vapor environment so as to cause a substitution of Tl by Hg without substantial alteration of the crystalline structure of the starting films. Preferably, a body comprising a substrate having an epitaxial Tl-containing film thereon is annealed under vacuum conditions with a Hg-based bulk; typical annealing conditions are 600-900° C. for a period of from about 1-20 hours. The final Hg-containing film products have a Jc of at least about 106 A/cm2 (100 K, OT) and a Xmin of up to about 50%. The thermoelectric materials are prepared by perturbing a crystalline precursor having a structure similar to the final material so as to cause a first molecule to be released from the precursor.Type: ApplicationFiled: April 27, 2001Publication date: May 9, 2002Inventors: Judy Wu, Shao Lin Yan, Yiyuan Xie

Patent number: 6289576Abstract: Superconducting, oxidic ceramic materials are worked to filamentary conductors, in that they are filled into silver tubes (2), drawn with the latter to filamentary conductors and then sintered under flowing oxygen. So that such filamentary conductors can be produced industrially with an adequate quality, drawing speed and yield, the silver tube (2) as a sintered sleeve is brought into contact with the ceramic material (1) in a drawing sleeve (3), of soft annealed steel (35) and the resulting sleeve combination undergoes the drawing stages. After drawing the steel drawing sleeve is removed by etching. In a large number of drawing stages, it is necessary to remove the drawing sleeve which has become hard due to the cold working and to replace it by a new, soft annealed sleeve. Simultaneously the sintering sleeve can undergo soft annealing.Type: GrantFiled: May 3, 1999Date of Patent: September 18, 2001Assignee: VOCO Draht AGInventors: Peter Wachter, Oscar Vogt, Rolf A.

Patent number: 5506196Abstract: A super conducting material is disclosed which exhibits super conducting properties at higher temperatures than known so far. The super conducting by the invented materials is exhibited at temperatures of over 110.degree. K. Various combinations of the components exhibits superconductivities even at temperatures of around 273.degree. K. or even around 300.degree. K. Contrary to known art superconducting materials, which require super cooled conditions and are suited only to sophisticated applications, and thereby have limited applications, the materials of this inventions do not always require super cooled conditions are suited for limitless applications and can work even at room temperature conditions. While a large range of choice of materials are suggested a few important combinations are made of oxides of Bismuth, Barium and Copper. Replacement of Barium by Thallium gives additional advantages.Type: GrantFiled: August 16, 1993Date of Patent: April 9, 1996Assignee: Magnetic Power, Inc.Inventor: Mihir Sen
