Effect of pressure on crystallization in lithium disilicate glass
Keywords and Phrases
Lithium disilicate glass
"The crystallization of a Li₂Oʺ2SiO₂ (LS₂) glass subjected to a uniform hydrostatic pressue of 4.5 or 6 GPa was investigated up to a temperature of 750 degrees C. At a pressure of 4.5 GPa crystal of lithium disilicate crystallizes from the glass while at 6 GPa, the densified glass crystallizes to a new high pressure form of lithium silicate. The crystal growth rate curve shifts to higher temperatures with increasing pressure. Change in the net value of viscosity at high pressure is believed to be responsible for the observed shift. The structure of the processed samples and the new high pressure crystalline phase were investigated using XRD, TEM, IR, Raman and NMR spectroscopy"--Abstract, leaf v.
