Crystallization and Morphological Evolution of Yttrium Carbonate李永绣,黄婷,黎敏,周雪珍,罗军明,何小彬摘 要:The crystallization and morphological evolution of yttrium... and 3-D regulate grain particles. However, X-ray patterns of all the crystalline yttrium carbonates are identified with the structure of tengerite Y2(CO3)3·2H2O. These facts demonstrate......
evolution can be divided into four steps: the initial rapid coarsening, structure separation, spheroidization and final coarsening. Correspondingly, these four steps result from the phase transformations of β... remelting and their relations with the microstructural evolution can be schematically presented by Fig.8. This indicates that the initial coarsening is due to the reaction of β→α, the structure separation......
