Incorporation of Nb and Ta into Calcium Borate Sol−Gel Glasses and Their Impact on the Structure and Properties

The effects of incorporating Nb2O5 or Ta2O5, both intermediate oxides, on the structure and ion release behavior of calcium borate-based sol−gel glasses [(70 − x)B2O3-30CaO-xM2O5, x = 0, 2.5, 5, and 7.5 (mol%), and M = Nb or Ta] were investigated. The glasses were prepared by dis...
