| Outline of Final Research Achievements |
Radiative characteristics and structure of rare-earth oxide film coated on C/C composite material was investigated for fundamental study to develop generation mudule, which converts huge radiant energy discharged through iron manufacturing process into electricity using photovoltaic cells. Normal spectral emittance of alumina plates coated with a lime glaze-based Er oxide film was measured at the temperature of 1000 ℃. As a result, it was revealed that the emittance in the wavelength of 1.55μｍ, which was the highest peak of emittance of Er, approached to almost the maximum value when compound ratio of Er2O3 to a total pigment was 50 wt%. This is because the lime glaze (bulk amorphous film) can contain the maximum amount of Er in the component. In addition, it was shown that reactive products and the optimum coating condition were different for lime a lime glaze-based Yb oxide film.
