In order to maintain electrical neutrality, some trivalent b ions oxidized to form b4 +, which resulted in a net decrease in the average radius of the b ions, as a result the volume of the unit cell decreases
為保持電中性,一些三價的b離子氧化變成四價的b離子,這一變化導致b位離子平均半徑的減小,從而導致晶胞的整體減小。The diffraction peak angle does n ' t change obviously as co / fe ratio, it is attributed to the radius of co fe ions are fairly similar, so the influence of substitutions on unit cell is small
而隨著co fe比的變化,衍射峰角度值變化不明顯,這是由於co 、 fe離子半徑相差不大,它們之間的位置取代對晶胞的整體影響相對較小。According to the sample prepared by hydrothermal method, the doping cations can enter the spinel lattice. rare earth cations mostly occupy position b because of their big radius. cerium are oxidized to ce4 +, whose radius is relatively small, and ce4 + mostly occupies position a. as a whole, the coercivity of cobalt ferrite doped with rare earth element is bigger than that of pure cobalt ferrite
結果表明,對水熱法制備的鐵氧體粒子,雜質離子能夠進入其尖晶石晶格中,並因稀土離子的半徑較大,而絕大部分佔據尖晶石的b位,鈰元素因被氧化成為四價離子,離子半徑相對較小,而主要佔據a位。
