Title: Formation of superconducting thin film
Inventor: NAKANISHI SHUSUKE
IPC: H01L39/24
Filed: 1991-03-08
Abstract: PURPOSE:To form a superconducting thin film free of cracks at the time of forming an oxide-based superconducting thin film with an Si wafer as the substrate by forming a buffer layer in the plural regions on the film forming surface on the wafer isolated from one another, and forming the superconducting thin film thereon. CONSTITUTION:A buffer layer 2 is formed only in the specified region on an Si wafer 1 to form regions la with the wafer 1 exposed between the buffer layer 2. An oxide-based superconducting film 3 of YBa2Cu3Oy is formed on the wafer 1 carrying the buffer layer 2. Since the crystal is not well grown in the superconducting thin film on the region la where the wafer 1 is exposed and the polycrystal is formed, the thin film is brittle as compared with the crystallized thin film on the buffer layer 2, cracks are concentrated on the thin film on the region 1a when cooled, hence the superconducting thin film formed on the buffer layer 2 is not substantially cracked, and an oxide superconducting thin film is mass-produced by using an easily available large- area Si wafer as the substrate.

Abstract: PURPOSE:To form a shell to a gel sphere and to simultaneously form a hollow part in the sphere by coating the surface of the core material of the gel sphere formed from an aqueous polysaccharide solution with a powder of a shell forming material and dehydrating the gel sphere by heat treatment. CONSTITUTION:At first, an aqueous solution of polysaccharide such as alginic acid or sodium alginate is dispersed in a gelling solution composed of an aqueous solution of calcium chloride or silver chloride to form a gel sphere becoming a core material. Next, the surface of the core material is coated with a powder of a shell forming material, for example, various ceramics, cement or a metal material such as iron. At this time, the moisture in the gel sphere transfers to the surface thereof to be absorbed in the powder layer. Finally, the gel sphere is heat-treated to dehydrate the powder layer containing the moisture absorbed from the gel sphere and, at the same time, a hollow part is formed in a shell. By this method, a light hollow sphere having high strength and excellent in heat insulating properties can be prepared in an extremely easy manner.
