rare earths%far infrared radiation ceramics%activated water%far infrared emissivity%surface tension
A kind of far infrared radiation ceramics was prepared by using silicate minerals, calcium carbonate and silicon dioxide as main raw materials, and cerium nitrate as additive. The structure of the ceramics and far infrared radiation properties on the surface tension of water were characterized by X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy and a tensiometer, respectively. It was showed that, after being sintered at 1160 °C, the solid solution was formed by CeO2 and Fe2O3, thus the crystal parameters (c/a axis ratio) and interplanar spacing of Fe2O3 increased. The addition of cerium was regarded to improve the far infrared radiation of ceramics, and the maximum emissivity value in the range of 5-20μm was 0.94. The surface tension of water gradually decreased with increasing radiation time.
