AbstractThe ivnention relates to an electric heater and its preparation method. There are several layers on outer surface of base body of the electric heater, which includes far infrared radiation metal based nano film, a layer of quartz glass powder and a compound conductive nano film of stannic (antimony) oxide. The compound conductive film can excite the far infrared radiation metal based nano film to produce far infrared heat effect with wider range of wavelength and higher radiant intensity. Wavelength of the far infrared radiation is within 3-600 microns. The invented electric heater has features of high thermal efficiency, without any harmful radiation and easy to use.
