Phase transformation of zirconia in sulfated zirconia-LiCl system
- 化学化工－已发表论文 
The phase transformation from tetragonal to monoclinic of zirconia for a series of sulfated zirconia-LiCl samples was characterized by ultraviolet Raman spectroscopy (UVRS) and X-ray diffraction (XRD). Results show that such phase transformation increases with increasing LiCl content and the monoclinic phase is first detected by XRD than that by UVRS for the sample with Li content of 0.5 wt.%. The comparison between XRD and UVRS characterizations indicates that the phase transition takes place initially at the core. (c) 2006 Elsevier B.V. All rights reserved.
