摘要:
A method of producing an electrode by applying onto a core material a solution of at least one metal salt and subjecting the resultant core material to a heat treatment in a heating zone, characterized in that said heat treatment comprises continuously elevating the temperature of the resultant core material to a temperature of about 400.degree. to 700.degree. C. over a period of about 5 minutes to 2 hours, while blowing air into the heating zone to obtain a coated electrode. The coated electrode produced according to the method of the present invention is excellent in adherence of the coating to the core material and has long life due to low losses of the coating during use.

摘要:
The present invention provides a metallic coating having a sheen and having a discontinuous structure at high productivity and low cost by using sputtering. A resin product includes a resin base material, and a metallic coating having a sheen and a discontinuous structure that is deposited on the resin base material so as to include a portion in which a high-formation metal that relatively readily forms a discontinuous structure when using vacuum vapor deposition is sputtered, and thereafter, a low-formation metal that does not relatively readily form a discontinuous structure when using vacuum vapor deposition is sputtered. The high-formation metal and the low-formation metal are selected from at least two species of metals whose crystal structures are identical and whose lattice constant difference is within 10%.

摘要:
Nitrates, such as alkali metal nitrates and ammonium nitrate, are electrolytically reduced to the corresponding nitrites by a process wherein an aqueous solution containing a nitrate is supplied into a cathode chamber of an electrolytic cell including cathode and anode chambers separated by a cation exchange membrane and an electric current is applied to the electrolytic cell, while maintaining the pH of the aqueous solution at a value of at least about 4. This process can be advantageously applied not only to the manufacture of nitrites but, also, to the treatment of waste nitrates. In the treatment of waste ammonium nitrate, the ammonium nitrite so formed is conveniently further treated by subjecting the electrolytically reduced catholyte to thermal decomposition outside the electrolytic cell, and removing the so formed nitrogen and water from the reaction system.
摘要:
A homogeneous cation exchange membrane having at least one roughened surface, which is assembled in an electrolytic cell with the roughened surface facing toward the cathode side of the cell, is employed in the electrolysis of an alkali chloride in an electrolytic cell divided by a cation exchange membrane into an anode compartment and a cathode compartment to produce an alkali hydroxide. The electrolysis voltage can be considerably reduced at a high current efficiency to provide a great economical advantage.
摘要:
Disclosed is a coating material for forming a gas barrier. The coating material includes a polyalcohol polymer, a polycarboxylic acid polymer, and a divalent or higher-valent metal compound whose surface is coated with a poorly water-soluble component, or alternatively a monovalent metal compound whose surface is coated with a poorly water-soluble component and a divalent or higher-valent metal compound whose surface is coated with a poorly water-soluble component. By applying this coating material to a plastic substrate layer, a gas-barrier multilayer body having a gas-barrier layer formed thereon is obtained.
