Study on Transitional Metal Oxides Energy-Saving Materials with High-Emissivity

Abstract:

In order to enhance the thermal efficiency of heating and dring facilities, the energy-saving high infrared radiation materials were synthesized by the solid state method for 2h at 950, 1050 and 1150 °C, respectively, and rapid cooling in the air, from transitional metal oxides Fe₂O₃, Cr₂O₃, MnO₂ andCuO. The strcture and emission property of the samples were characterized through X-ray diffractomete, scanning electron microscop and infrared radiation meter. The results show that the main phases of resultants are spinel ferrites, and with increasing temperature, crystals become better and multiple spinel and like-spinel structures are formed. The infrared radiance represents a nonlinear variation with calcining temperature. The coatings on the stainless steel surface prepared with the materials with self-made binders have good infrared radiation, up to a maximum of 0.90, and have perfect resistance to thermal shock and may arrive at 25 times (RT←→800 °C), exhibiting fairly high binding strength. So the materials which are apply to on the internal wall of heating and drying facilities are believed to result in an long-term energy conservation.
