Structure, Glass Stability and Crystallization Activation Energy of SrO-CaO-B2O3-SiO2 glasses doped with TiO2

[EN] By the first time the correlation between glass stability (GS), activation energy for crystallization (E) and structural data was investigated for some TiOdoped CaO-SrO-BO-SiO glasses obtained from the same batch. B NMR spectra demonstrated that the boron changes from tetragonal to trigonal con...

It was demonstrated that all these glasses crystallize mainly from the surface, and the crystal growth changes with the TiO content.

This dramatic reduction in E is strongly correlated to the change in the role of Ti cation in the glass matrix.The authors are indebted to the Maranh ̃o Foundation for Scientific Research and Development (FAPEMA), Processes # 2014/01469, #2014/00260 and # 2015/00773.
