Title:
PERMANENT MAGNET, AND METHOD FOR PRODUCING PERMANENT MAGNET
Document Type and Number:
WIPO Patent Application WO/2011/142275
Kind Code:
A1
Abstract:
Provided are a permanent magnet and a method for producing a permanent magnet, wherein it is possible to produce metal alkoxide by means of a simplified production facility and manufacturing process, and to cut manufacturing costs. An electrolyte is formed by dissolving chloride or by injecting hydrogen chloride gas into an alcohol, which is the same as the alcohol that is a structural component of the metal alkoxide to be produced. Subsequently a metal alkoxide alcohol solution is obtained by performing electrolysis on the electrolyte using: as the anode, a ferroalloy containing Fe and a metal which is a structural component of the metal alkoxide to be produced at a predetermined weight ratio (e.g., 1:1); and, as the cathode, the same ferroalloy, carbon, platinum, or stainless steel. A permanent magnet is produced by using the metal alkoxide alcohol solution thus obtained.
