Preparation and characterization of fresnoite crystal with Na2O-TiO2-GeO2 glass change in glass network former |
| 초록 |
In this study, Na2O-TiO2-GeO2 (NTG) glass was prepared to observe the effect of glass network former exchange(SiO2→GeO2). The prepared mother glass ion exchge(Na→Ba) in which fresnoite crystallines were formed on the surface of the mother glass. For NTG glass, the depth of fresnoite crystal is decreased by the ion radius difference Na(0.097nm) and Ba(0.134nm) when the ion-exchange process. In order to solve this problem, we tried to exchange glass network former element. The crystalline phase of the soaked glasses was examined by means of X-ray diffraction (XRD) by the different glass network former. The structure and composition of the strontium ions exchanged crystalline was analyzed by Scanning electron microscopy-energy dispersive X-ray spectrometer(SEM-EDS). Nd:YAG laser (1064nm) were used to observe the crystalline phase of depth, structure and second order nonlinear property. |
