Effect of the addition of TiO 2 , ZrO 2 , V 2 O 5 and Nb 2 O 5 on the stability parameters of the Li 2 O–BaO–SiO 2 glass

Effects of TiO2 and P2O5 on solarization and crystallization of photosensitive lithium silicate glass

“…It is noteworthy that manipulation of both composition and heat treatment schedule would be able to bring desirable properties [7][8][9]. Another nucleating agent in the preparation of glass ceramics can be TiO 2 a member of 3d transition metal oxides [10][11][12].…”

Role of vanadium oxide on the lithium silicate glass structure and properties

“…V 2 O 5 and ZnO additions were shown to delay the crystallization process in BaO–CaO–SiO 2 glasses 13 . In MgO–Al 2 O 3 ‐SiO 2 –TiO 2 ‐based glasses, the addition of 1.0–1.2 mol% of V 2 O 5 was found to increase the degree of crystallization after a two‐step heat treatment process 14 and, in Li 2 O–BaO–SiO 2 ‐based glasses, V 2 O 5 decreases the glass stability and acts as a nucleating agent 15 . The crystallization of glasses in the ternary CaO–ZrO 2 ‐SiO 2 system doped with ~0.0‐5.0 mol % V 2 O 5 was found to be predominantly controlled by a surface nucleation mechanism with the crystallization activation energy values showing a parabolically decreasing trend 16 .…”

Properties of Foam Glass Material Modified by Nanosize Zirconium Dioxide

“…These phenomena are the basis for using zirconium dioxide as an opacifier in the production of white enamels. ZrO 2 also effectively stimulates crystallization, which is used in the production of glass ceramic materials [12]. Zirconium dioxide is less effective in influencing the behavior of silicate melt when nanosize particles are used.…”
