Sorted by: Date Added To NTRS in Descending order In-Situ Crystallization of a Lithium Disilicate Glass--Effect of Pressure on Crystal Growth Rate Author(s): Fuss, T.; Ray, C. S.; Lesher, C. E.; Day, D. E. Abstract: Crystallization of a Li2O.2SiO2 (LS2) glass subjected to a uniform hydrostatic pressure of 4.5 GPa and 6 GPa was investigated up to a temperature of 750 C. The density of the compressed glass is about 2 greater at 4.5 GPa ... NASA Center: Marshall Space Flight Center Publication Year: 2006 Added to NTRS: 2008-04-01 Document ID: 20080009664 Isothermal Analysis of the Crystallization Kinetics in Lithium Disilicate Glass using Trans Temp Furnace Author(s): Fuss, T.; Ray, C. S.; Day, D. E. Abstract: Crystallization kinetics for lithium disilicate, Li2O2SiO2, (LS2) glass has been studied extensively by nonisothermal methods, but only a few studies on the isothermal crystallization kinetics of LS2 are available. In the ... NASA Center: Marshall Space Flight Center Publication Year: 2006 Added to NTRS: 2007-02-07 Document ID: 20070002144 XRD, TEM, IR, Raman and NMR Spectroscopy of In Situ Crystallization of Lithium Disilicate Glass Author(s): Fuss, T.; Mogus-Milankovic, A.; Ray, C. S.; Lesher, C. E.; Youngman, R.; Day, D. E. Abstract: The structure of a Li2O-2SiO2 (LS2) glass was investigated as a function of pressure and temperature up to 6 GPa and 750 C respectively, using XRD, TEM, IR, Raman and NMR spectroscopy. Glass densified at 6 GPa has an average ... NASA Center: Marshall Space Flight Center Publication Year: 2006 Added to NTRS: 2006-09-29 Document ID: 20060024726 Crystallization of a Li2O2SiO2 Glass under High Hydrostatic Pressures Author(s): Fuss, T.; Day, D. E.; Lesher, C. E.; Ray, C. S. Abstract: The crystallization behavior of a Li2O.2SiO2 (LS2) glass subjected to a uniform hydrostatic pressure of 4.5 or 6 GPa was investigated between 550 and 800 C using XRD, IR, Raman, TEM, NMR, and DTA. The density of the glass ...
