    Abstract: PURPOSE: To readily obtain a diaryl carbonate in good yield without using phosgene which is a compound having strong toxicity by carrying out a decarbonylation reaction of a diaryl oxalate at a specific temperature. CONSTITUTION: A diaryl oxalate is subjected to a decarbonylation reaction at 330-800 deg.C, especially 450-650 deg.C in a vapor phase. Furthermore, specifically, e.g. (A) the diaryl oxalate dissolved in a solid, a melted liquid or a solvent is previously vaporized and fed to a reactor together with (B) an inert gas such as nitrogen gas and (C) an inert filler such as quartz having no acid point, hydroxyl group, etc., in a feed amount of 10-1000g/L.hr (L is a unit volume; hr is a unit time) and a space velocity of 100-6000hr and then, the reaction of the diaryl oxalate is carried out under ordinary or reduced pressure.

    Abstract: PURPOSE:To produce a Bi-Sr-Ca-Cu-O superconducting thin film with the (110) face selectively grown and oriented with respect to the substrate surface and appropriate to prepare the Josephson junction device, three-terminal device, etc. CONSTITUTION:A Bi-Sr-Ca-Cu-O superconducting thin film is formed on a substrate consisting of an MgO [110] single crystal by chemical vapor deposition, and the (110) face is selectively grown with respect to the substrate surface. Consequently, Bi-Sr-Ca-Cu-O superconducting thin film extremely effective for the Josephson junction device, three-terminal device, etc., is obtained by chemical vapor deposition.

    Abstract: PURPOSE:To obtain an oxide superconductor having improved high-temperature stability by depositing an oxide superconductor composed of a rare-earth element, Ba, Cu and O at specific compositional ratios on a substrate by a vapor- phase growth process using O2 gas and an organic metal gas containing rare- earth element, Ba and Cu. CONSTITUTION:Organic metal raw materials containing a rare-earth element (e.g. Y and La), Ba and Cu respectively are prepared in such a manner as to give a vapor mixture of the above components having ratios of the objective superconductor (i.e., 1:2:4) and the vapor is added with O2 to obtain a mixed gas. The mixed gas is introduced into a quartz-made reactor 1 under an O2 partial pressure of 7.5-34 Torr through a mixed gas inlet port 2. A substrate 5 made of MgO or SrTiO3 and attached to a susceptor 4 placed in the middle of the reactor 1 is heated with a high-frequency coil 6 and, at the same time, the mixed gas is heated at 700-840 deg.C to deposit an oxide film containing an oxide superconductor on the surface of the substrate 5. The oxide is etched by dry-etching to obtain an oxide superconductor (e.g. YBa2Cu4O8) stable at high temperature.
