Paper Title:
Effect of Forming Pressure and Sintering Temperature on Thermal Expansion Property of Li2O-Al2O3-P2O5-SiO2 Glass-Ceramics
  Abstract

Li2O-Al2O3-P2O5-SiO2 xerogel powders were synthesized by sol-gel route and glass-ceramics were prepared under different forming pressure and sintering temperature. The effects of sintering temperature and forming pressure on coefficient of thermal expansion of prepared glass-ceramics were investigated by means of DTA-TG, TEC and XRD. The results indicate that xerogel powders crystallization begins at 785°C, and the main crystallite phases in the researched specimens are virgilite and cristobalite. The TEC decreases linearly with the forming pressure. When the sintering temperature is 950°C and forming pressure is 40MPa, a low TEC of 0.65×10-6 °C-1 can be obtained.
