Increasing Temperature

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.

Gel Processing

AbstractSol-gel synthesis of transitional metal oxides is one of the important technique to obtain the pure and homogenous materials at low temperature. In this work, Barium strontium titantate (BST) was synthesized by sol-gel processing using 2,4-pentadionate as the precursors of metal oxides. The Ba1−xSrxTiO3 was prepared for four values of x i.e. 0.2, 0.4, 0.5 and 0.6. The obtained powders were heated from 400 °C to 800 °C at the interval of 100 °C to determine the temperature of crystallization. The phase of the final products was investigated by x-ray diffraction (XRD). Two particle sizes (< 100 nm and 200-400 nm) were observed under the scanning electron microscope (SEM) of the heat treated xerogel. The dielectric properties were determined by impedance analyzer at the frequency of 1MHz and explained in detail for the different values of x.
