Cristobalite is known to precipitate out of borosilicate glass (Coming
7740) and a binary glass mixture of borosilicate glass and high silic
a glass when these glasses are heated to elevated temperatures. To pre
vent cristobalite from forming in these glass systems, a devitrificati
on inhibitor needs to be found. Among oxides selected for testing, bot
h Al2O3 and Ga2O3 are found to prevent cristobalite from forming in th
ese glass systems.
