with the formation of the Sm2Fe17 phase from the very beginning of the reaction,and rich samarium phases,such as SmFe2 and SmFe3,were not formed,and the rate-determining step of the R/D reaction was found to be the peritectic reaction between liquid samarium and solid iron.关键词:......
">Bi1-xSmxFeO3 (x=0.00-0.15) ceramics were synthesized by sol-gel technique with rapid liquid phase sintering process to study the effects of samarium (Sm) substitution on their microstructure and properties. X-ray diffraction (XRD) and Raman studies showed that the structure of BiFeO3 was changed from rhombohedral to orthorhombic at the samarium substitution concentration about x=0.10. The SEM......

% although decreased slightly with the increasing content of samarium, indicating that the excessive A-site element was helpful to enhance their sinterability. Conductivities of the specimens in air increased......
results in a large network structure. With the increase of samarium oxide, the silicate coordination Q4 (3T) will have predominance gradually. Heat-treatment has little effect on the boron and aluminum......
