27Al NMR study of the structure of lanthanum- and yttrium-based aluminosilicate glasses and melts.
We have investigated by (27)Al nuclear magnetic resonance spectroscopy some compositions in the Ln(2)O(3)-Al(2)O(3)-SiO2 (Ln = Y or La) ternary phase diagram containing more than 60 mol % of SiO2. One- and two-dimensional high-field (17.6 T) high-speed (30 kHz) magic angle spinning experiments have been performed along with simulations of the spectra to quantify the amount of penta-coordinated ...
متن کاملMolecular Struct’ure and Crystallization Behavior of Chalcogenide Glasses
Isothermal crystallization of ternary (Ge,S,), -X(Sn,S,), glasses is examined over the glass forming range 0 < x < 0.6. Time-temperature-transformation (TIT) curves are obtained using scanning calorimetry. The results show that both nucleation and growth processes dominate crystallization of the glasses in the range 0 < .Y < 0.25, but only growth processes are found to occur once x 2 0.25. The ...
متن کاملAn Investigation into the Effects of Composition and BaF2 Content on the Structure and Crystallization Behavior of SiO2-Al2O3-K2O-BaF2 Oxyfluoride Glasses
Nowadays, oxyfluoride glasses have received much attention from photonic researchers as they benefit from the advantages of both oxide and fluoride glasses (low phonon energy in parallel with high mechanical and chemical durability). The purppose of this paper was to study the different glass compositions in SiO2-Al2O3-K2O-BaF2 system and i...
متن کاملEffect of P2O5 on Crystallization Behavior and Chemical Resistance of Dental Glasses in the Li2O-SiO2-ZrO2 System
Commercial dental lithium disilicate based glass-ceramics containing various amounts of P2O5 were synthesized. Regarding the crystallization behavior and physico-chemical properties of the glasses, the optimum percent of P2O5 was determined.as 8 %wt. Crystallization behavior of the glasses was investigated by X-ray diffraction (XRD) and differential thermal analysis (DTA). The micro-hardness a...
متن کاملCrystallization of Liquids and Glasses
The scientific and technological importance of advanced materials are summarized. The goverriing theories of glass transition, crystal nucleation and crystal growth are combined with t he overall theory of transformation kinetics to clarify the phenomenon of glass formation from the liquid state. Finally, examples of novel glasses as well as gIassceramics obtained from the controlled crystalliz...
