【摘要】：以攀西地区高炉废渣为原料,采用陶瓷烧结工艺制备了不同稀土Ce掺杂量的高炉渣远红外陶瓷。研究了高炉渣陶瓷中稀土Ce的最佳掺入量以及稀土的掺入对陶瓷红外辐射性能的影响机理,考察了稀土的掺入对于高炉渣陶瓷线收缩率、吸水率及抗折强度的影响。采用X射线衍射与扫描电子显微镜研究了样品的晶相组成与显微结构,采用Fourier红外吸收光谱及发射光谱研究了样品红外吸收及发射性能。结果表明:陶瓷红外发射率最高达0.91,样品的抗折强度最高达38.1 MPa。高炉渣远红外陶瓷不仅具备高的远红外辐射能力,而且拥有良好的物理性能。
[Abstract]:Using blast furnace slag in Panxi area as raw material, different rare earth ce doped blast furnace slag far infrared ceramics were prepared by ceramic sintering process. The optimum amount of rare earth ce in blast furnace slag ceramics and the influence mechanism of rare earth doping on infrared radiation properties of ceramics were studied. The effects of rare earth addition on line shrinkage, water absorption and flexural strength of blast furnace slag ceramics were investigated. The crystal phase composition and microstructure of the samples were studied by X-ray diffraction and scanning electron microscopy. The infrared absorption and emission properties of the samples were studied by Fourier infrared absorption and emission spectra. The results show that the highest infrared emissivity is 0.91and the flexural strength is 38.1 MPa. Blast furnace slag far-infrared ceramics not only have high far-infrared radiation ability, but also have good physical properties.
