Abstract

Dense (similar to 98.5%), lithium aluminum silicate glass-ceramics were obtained via the sinter-crystallization of glass particle compacts at relatively low temperatures, that is, 790-875 degrees C. The effect of P2O5 on the glass-ceramics' sinter-crystallization behavior was evaluated. We found that P2O5 does not modify the surface crystallization mechanism but instead delays the crystallization kinetics, which facilitates viscous flow sintering. Our glass-ceramics had virgilite (LixAlxSi3-xO6; 0.5 < x < 1), a crystal size <1 m, and a linear thermal expansion coefficient of 2.1 x 10(-6)degrees C-1 in the temperature range 40-500 degrees C. The overall heat treatment to obtain these GCs was quite short, at similar to 25 min. (AU)
