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

A one-step synthesis of rare-earth phosphate–borosilicate glass composites

“…55 Y 3+ has been shown to break up the glass network or strengthen it in silicate glasses depending on composition and therefore it has been suggested that Y 3+ can be classied as a network intermediate. 51,59 This was also suggested to be true by Malchukova et al for Gd 3+ , which has a similar eld strength to Y 3+ (0.55). 18 In that study, Gd was doped into aluminoborosilicate glass (0-4.4 wt% of Gd 2 O 3 ) and exposed to radiation in order to determine how these conditions effects the potential waste form.…”

Non-crystallising glass sealants for SOFC: Effect of Y2O3 addition

“…At the same time, non-crystallising sealants have received little attention. The glass of 30BaO-40SiO 2 -20B 2 O 3 -10Y 2 O 3 composition was shown to be stable after exposure at 800°C for 100 h. The sample studied remained predominantly amorphous and the change of CTE value was only 3% which indicates the high stability of the amorphous state [12]. A similar result was observed for the glass of the same composition in which BaO was replaced by CaO [13].…”

Optical Properties of SiO2 – TiO2 – La2O3 – Na2O – Y2O3 Glasses and A Novel Process of Preparing the Parent Glass-Ceramics

“…Y2O3 enhances the host glass matrix's physical structure and mechanical strength. [32][33][34][35][36][37][38]. The existence of Y2O3 enhances the capacity to form glass and reduces devitrification.…”
