The present invention relates to a high-heat dissipation ceramic composite and, more particularly, to a heat dissipation ceramic composite which is a metal oxide composite comprising an iron oxide, a silicon oxide, a magnesium oxide, and an aluminum oxide, wherein the metal oxide is a metal oxide which is quenched after being melted. When a heat-dissipating coating surface treatment is carried out by using the high-heat dissipation ceramic composite of the present invention, the total amount of radiation is increased since the radiative rate on a surface is improved, and particularly, a high radiative rate is exhibited at room temperature and even at a high temperature of 350 degrees or more so as to prevent reduction in the radiative rate caused by an increase of temperature, and thus, cooling efficiency of components by heat dissipation is increased so as to properly control the temperature of heating components, thereby improving the performance and life of the components. |
