title: [Study on thermal treatment schedule of leucite microcrystallization to reinforce dental glass ceramics].
abstract: OBJECTIVE
  To explore the thermal treatment schedule of leucite microcrystallization to reinforce dental glass ceramics.
  
  
  METHODS
  After component analysis and selection, the raw material were treated by different temperature schedules. The products were analyzed by polaring microscope and X-ray diffractometer to determine the appropriate thermal treatment schedule.
  
  
  RESULTS
  The temperature of melting, nuclearing and crystalizing was 1,600 degrees C, 1,200 degrees C and 1,500 degrees C. Leucite microcrystals dispersed in the glass matrix evenly and the size of leucite particle was about 0.8 micro m.
  
  
  CONCLUSIONS
  Leucite can be microcrystalized according to an appropriate thermal treatment schedule.
