摘要：

The sol-gl route was successfully used to prepare a glass-ceramic material of the stoichiometric composition Sr0.5Ba0.5Al2Si2O8. The sol-gel powder was cold isostatic pressed and sintered at 300, 980, 1040, 1300 and 1500 degrees C. X-ray analyses were then performed. These showed that monocelsian could be crystallised at temperatures as low as 1040 degrees C. The addition of strontium oxide appears to enhance the hexacelsian to celsian transformation. This result makes the Sr(0.5)Bao(0.5)Al(2)Si(2)O(8) glass-ceramic a potential matrix for thermostructural composites.
