Metal oxide composition heated by microwave irradiation, organic/inorganic composition and product comprising the same

PURPOSE: A metal oxide contained composition, organic and inorganic composition including the same and a secondary processed product are provided to enhance heat emitting effects during microwave irradiation. CONSTITUTION: A metal oxide contained composition includes 4 wt% of one or more iron oxide compound among Fe2O3, Fe3O4 and FeO, and is emits heat by 300MHz-300GHz of microwave. The metal oxide contained composition additionally contains 1 wt% or greater of Al2O3. The metal oxide contained composition is one or greater selected from a group containing a rapid cooling steelmaking slag composition (particle size of 10mm or less and the sphericity rate of 0.5), an annealing steelmaking slag composition (particle size of 10mm or less), a copper smelting slag composition (particle size of 10mm or less), zinc making slag composition (particle size of 10mm or less), red mud composition (particle size of 1mm or less), hematite composition (particle size of 25mm or less), refined Fly ash composition(particle size of 10mm or less) and refined loess composition(particle size of 1mm or less). [Reference numerals] (AA) Raw materials(rapid cooling steel making slag); (BB) Sorting by particle size; (CC) Sorting by magnetism; (DD) Sorting by form; (EE) Utilizing for other use
