FT-IR and thermograph were used to investigate the infrared radiation characteristics of film made by the sol-gel method. FT-IR spectrum of the film showed high infrared absorption by Si-O-Si vibration at 1220, 1080, 800 and cm The infrared absorption and radiation wavelength ranges of the film measured by the integration method coincided with the reflection method, and the infrared emissivity was 0.65, equally. Depending on the bonding of elements, the infrared emissivity was high in the wavelength range where the infrared absorption rate was high, that follows the Kirchhoff's law. The emissivity showed the highest value in the wavelength range between . film was considered as an efficient materials for infrared radiator at temperature below 10. The heat radiation temperature was for the aluminum plate, but for the film after 7 minutes heat absorption, consiquently, higher than the former.
