METHOD FOR PRODUCING ELECTROCONDUCTIVE OXIDE SHORT FIBER

摘要

PROBLEM TO BE SOLVED: To provide a method for simply producing electroconductive oxide short fibers at a low cost with small energy consumption by using water as a solvent. SOLUTION: The method for production is carried out as follows. One or two or more kinds of water-soluble metal compounds are dissolved in water so that the final fiber composition is the composition of the electroconductive oxide. A hydroxycarboxylic acid and a polyol are added to the aqueous solution and a thickener is then added to provide a spinning solution. The resultant spinning solution is spun to afford a fiber precursor, which is heat-treated. A perovskite type oxide such as an SnO2oxide or LaSrMnO3is cited as the resultant electroconductive oxide short fibers. COPYRIGHT: (C)2005,JPO&NCIPI
