FAR-INFRARED EMITTING MATERIALS HAVING HIGH FAR INFRARED RAY EMISSIVITY BY FORMING DEFECTS IN HIGH TEMPERATURE-STABLE OXIDES, OXYCARBIDES AND CARBIDE POWDER, AND A METHOD FOR PREPARING THE SAME
FAR-INFRARED EMITTING MATERIALS HAVING HIGH FAR INFRARED RAY EMISSIVITY BY FORMING DEFECTS IN HIGH TEMPERATURE-STABLE OXIDES, OXYCARBIDES AND CARBIDE POWDER, AND A METHOD FOR PREPARING THE SAME
PURPOSE: A far-infrared emitting materials having high far infrared ray emissivity is provided to exhibit the formation of void defects in high temperature-stable oxides, oxycarbides and carbide powder, crystalline structure variation through defects, and high infrared ray emissivity through substitutional solid solution.;CONSTITUTION: A non-stoichiometric compound powder has an AB_(1-x) composition(0.5=x=0) and can emit infrared rays of high efficiency, wherein A element is the transition metal belonging to Group 4b, 5b, and 6b(Ti, V, Cr) and B is the element selected from carbon(C), nitrogen(N) and oxygen(O). The solid solution powder is a complete solid solution compound having a (A1, A2, A3,..)(B1, B2, B3,..) composition, wherein A element is two kinds or more of transition metals selected from Group 4b, 5b, and 6b(Ti, V, Cr) in the periodic table and B element is one kind or more selected from carbon(C), nitrogen(N) and oxygen(O).;COPYRIGHT KIPO 2011
