Enhanced infrared radiation properties of MgFe2O4 doping with in-situ generated Fe2+ by adjusting the sintering temperature and atmosphere
Doping with transition metal ions can effectively improve the infrared performance of spinel materials; however, the high cost restricts its large-scale industrial application. Motivated by this, MgFe2O4 doping with in-situ generated Fe2+ was prepared by adjusting the sintering conditions. The influence of various sintering temperatures and atmospheres on the Fe2+ content was investigated, along with the effects of different Fe2+ doping levels on the infrared radiation properties of MgFe2O4. The mechanisms of in-situ formation of Fe2+ and Fe2+ doping in enhancing the infrared radiation properties of MgFe2O4 were discussed. Specifically, the specimen sintered in a reducing atmosphere at 1500 ℃ has the highest Fe2+ content, and also exhibit the highest average infrared emissivity in the 0.8–2.5 μm and 2.5–10 μm bands, which are 0.826 and 0.849, respectively.
期刊介绍：
The Journal of the European Ceramic Society publishes the results of original research and reviews relating to ceramic materials. Papers of either an experimental or theoretical character will be welcomed on a fully international basis. The emphasis is on novel generic science concerning the relationships between processing, microstructure and properties of polycrystalline ceramics consolidated at high temperature. Papers may relate to any of the conventional categories of ceramic: structural, functional, traditional or composite. The central objective is to sustain a high standard of research quality by means of appropriate reviewing procedures.
