Magnetic material having superconductive properties at room temperature and a method of preparation of the same

摘要

A super conducting material is disclosed which exhibits super conducting properties at higher temperature than known so far. The super conducting by the invented materials is exhibited at temperatures of over 110° K. Various combinations of the components exhibits superconductivities even at temperatures of around 273° K. or even around 300° 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 Thantalium gives additional advantages. The above materials can be formed into compacts, wire products or applied as thin coating on substrates made of refractory materials. In forming thin coatings on refractory substrates, use of buffer layer/s of Zirconia or silver oxide provided highly promising results. The invention also suggest suitable methods for the manufacture of different forms of the super-conducting material.
