PURPOSE: A composition for generating high temperature and electromagnetic wave is provided to have excellent photothermal property by absorbing visible ray or near infrared ray, thereby radiating electromagnetic wave in a far and near infrared ray region.CONSTITUTION: A composition for generating high temperature and electromagnetic wave comprises iron(III) hydroxide(Fe(OH)3, FeOOH) and is used for generating photothermal and electromagnetic wave by irradiating visible ray and far infra red ray. A method for generating photothermal and electromagnetic wave comprises a step of manufacturing a composition for generating high temperature and electromagnetic wave by combining one or more selected from a group selected from mud, red clay, barley stone, sericite, clay, and illite, into the iron hydroxide and a step of visible ray-near infra red ray-irradiating composition.COPYRIGHT KIPO 2013본 발명은 수산화철(Fe(OH)3, FeOOH)이 포함된 조성물의 가시광선 및 가시광선-근적외선 흡수에 의한 광열특성을 이용한 광열 및 전자기파발생 방법에 관한 것으로서, 이러한 방법에 의하면 발열효과 뿐만 아니라 수산화철(Fe(OH)3, FeOOH)로부터 방사되는 근적외선 및 원적외선 영역의 전자기파에 의해 더욱 효율적인 온열효과가 가능하다.
