掺杂稀土铈对高炉渣陶瓷远红外性能及物理性能的影响
Effect of Ce Doping on Far-Infrared Radiation and Physical Performance of Blast Furnace Slags Ceramic
摘要
Abstract
A series of far-infrared ceramics were prepared by a sintering process with blast furnace slags (Pan-xi region, China) as raw material with Ce as a dopant. The influence of rare earth element Ce on the far-infrared properties and mechanical properties (i.e., linear shrinkage, water absorption and bending strength) of blast furnace slags ceramics was investigated, and the optional Ce doping contents was determined. The phase composition and microstructure were characterized by X-ray diffraction and scanning electron microscopy,respectively. The far-infrared emission and absorption properties of samples were determined via the Fourier transform infrared spectroscopy.The results indicate that the maximum far-infrared emissivity of as-prepared samples is 0.91, and its bending strength is up to 38.1 MPa.Therefore, the developed blast furnace slags ceramics have the excellent ability of far-infrared radiation and mechanical properties.关键词
