Title:
METHOD FOR MANUFACTURING MgFe2O4 USABLE AS LIVING BODY HEATING MATERIAL AND MgFe2O4 OBTAINED THEREBY
Document Type and Number:
Japanese Patent JP2007238392
Kind Code:
A
Abstract:
To provide MgFe2O4with an improved exothermicity which is used as a living body heating material for cauterizing a diseased part by being kept in a living body and generating heat by an alternating current magnetic field.
An precursor solid in which respective elements are uniformly dispersed in a polymer is prepared by polymerizing an organic polymer in an aqueous solution in which Mg and Fe of a stoichiometric proportion are dissolved, and then the precursor solid is fired at 1,100°C or above to give MgFe2O4. Thus prepared MgFe2O4have a drastically improved exothermicity in an alternating current magnetic field as compared with that of MgFe2O4prepared by a conventional solid reaction method and a coprecipitation method.
