Non-isothermal crystallization kinetics of ZnO–BaO–B2O3–SiO2 glass

Effect of A2O3 (A=La, Y, Cr, Al) on thermal and crystallization kinetics of borosilicate glass sealants for solid oxide fuel cells

“…It is possible that Y 2 O 3 is associated with B 2 O 3 instead of SiO 2 network former which may prevent formation of boron and yttria rich crystalline phases in this glass. Our earlier reports [13,14] also indicated that the addition of Y 2 O 3 in any glass composition increase the stability of the glasses without forming any detrimental phase during the heat treatment.…”

“…Some of these phases are very detrimental due to their low thermal expansion. Therefore, based on earlier studies [13][14][15][16] on glass and glass ceramics a glass composition SiO 2 -B 2 O 3 -BaO-A 2 O 3 (A = Y, La, Al, Cr) was selected for the present study. Effect of field strength of intermediate cations on the crystallization kinetics, formation of various crystalline phases and change in thermal properties of the glasses are studied.…”

Crystallization of lithium disilicate-based multicomponent glasses – effect of silica/lithia ratio

“…The ratio between the ordinate of the DTA curve and the total area of the peak gives the corresponding crystallization rate (dχ/dt) [31]. From the plot of dχ/dt as a function of temperature for both exothermic peaks, shown in Fig.…”

Effect of titanium addition on crystallization kinetics of lithium borosilicate glass

“…It means that the higher amount of titanium in the glass network helps the process of nucleation and growth rate so; it needs less energy for nucleation and growth process for high amount of titanium glass samples. The values of the activation energy, E, were compared to those in related oxide glasses reported before and were in excellent agreement [23][24][25].…”
