SIOIC FIBER, METAL-DOPED SIOIC FIBER, MICROWAVE ABSORPTION AND HEATING ELEMENT COMPRISING SAME METAL-DOPED SIOIC FIBER, AND MANUFACTURING METHOD THEREFOR

WIPO Patent Application WO/2019/117473

A1

An embodiment of the present invention pertains to a SiOIC fiber comprising 30-50 % by weight of silicon(Si), 5-15 % by weight of oxygen (O), 3-15 % by weight of iodine (I), and 20-50 % by weight of carbon (C), a metal-doped SiOIC fiber comprising 3-30 % by weight of silicon (Si), 3-40 % by weight of oxygen (O), 5-50 % by weight of iodine (I), 5-40 % by weight of carbon (C), and 5-50 % by weight of a metal, a microwave absorption and heating element comprising the same metal-doped SiOIC fiber, and a manufacturing method therefor. According to the present invention, heating efficiency in response to microwaves can be remarkably increased and simultaneously, a remarkable improvement of durability can be brought about in the heating element by preventing or minimizing an oxygen-induced oxidative reaction.
