摘要：

Variations in glass transition temperature, onset of crystallization, thermal expansion coefficient, density and molar volume with B2O3 concentration were studied in a series of xB(2)O(3)-(100 - x)Ba(PO3)(2) glasses with 0-10 mol% B2O3. DTA analysis and isothermal treatments for powdered glass samples reveal that >= 7.5 mol% B2O3 addition suppresses surface crystallization during softening process. Raman spectroscopy suggests that the properties are related to the glass structure Consisting Of PO4 Q(2) units with diborate and PO4-BO4 groups. (c) 2006 Elsevier B.V. All rights reserved.
