NEW PRODUCTION OF CARBON MATERIAL COATED WITH METAL OXIDE

PROBLEM TO BE SOLVED: To produce a carbon material, e.g. carbon fibers coated with a ceramic material and expected to fine wide application to new fields of a composite material, an electronic material, etc., by a relatively low temperature energy- saving method. SOLUTION: An aqueous solution contai...

Zusammenfassung:	PROBLEM TO BE SOLVED: To produce a carbon material, e.g. carbon fibers coated with a ceramic material and expected to fine wide application to new fields of a composite material, an electronic material, etc., by a relatively low temperature energy- saving method. SOLUTION: An aqueous solution containing urea and metalic salts and a carbon material are put in a microwave transmissive vessel and irradiated with microwaves under pressure to uniformly precipitate metal oxides and multiple metal oxides onto the surface of the carbon. The metal oxides are ferromagnetic oxides and their multiple oxides and may be selected from iron oxide and ferrites that the iron multiple oxides. Reaction is carried out under microwave-hydrothermal conditions of
