本研究以SiO2-B2O3-Al2O3-CaO系陶瓷结合剂为研究对象,通过XRD、FTIR、DSC、SEM、抗折强度和热膨胀系数等先进结构与性能表征测试手段,发现:Li2O的掺入可明显降低陶瓷结合剂的烧结温度,促进锂辉石晶相的析出,并提高陶瓷结合剂的平均抗折强度;当Li2O含量为4.0%时,陶瓷结合剂烧结后的抗折强度达到126MPa,对应的最佳...
FTIR analysis shows that the amount of Fe-C(2+) increases for increasingly reducing conditions. FTIR data also provide strong evidence for slight but significant amounts of Li at the A sites.doi:10.1007/s00269-004-0402-2Iezzi GCamara FDella Ventura GOberti RPedrazzi GRobert JL...
Fourier transform infrared (FTIR) proves the co-existence of SiO_2 and ferrites in the products. The addition of SiO_2 nanoparticles promotes the formation of more homogeneous and finer ferrite crystal, as proved by scanning electron microscopy (SEM) . Compared with BaLa_(0.5)Fe_(11.5)O_(19...
The as-prepared Fe3O4@SiO2@MIP particles were characterized by transmission electron microscopy (TEM), vibrating sample magnetometer (VSM), and Fourier transform infrared spectroscopy (FTIR). The adsorption kinetics, isotherms and reusability were also investigated. Finally, the Fe3O4@SiO2@MIP ...
crystal-structureFTIR and Raman spectroscopyIn this work we report on a complete crystal-chemical characterization of a near end-member riebeckite from Malawi, and use the available data to critically compare information obtained from different analytical methods. The sample occurs as well-formed and...
