Gallium oxides [Jan. 6th, 2012|02:15 am]
Chemistry Help


Dear сolleagues,
I had an unsolved problem. I have a gallium oxide, which is a mixture of three modifications: α-, β- and ε-Ga2O3.

The question: is how to get rid of the β-Ga2O3 in this mixture?

P.S. Option, described in Wikipedia (heating β-Ga2O3 at 65 kbar and 1100 C) is not considered, the pressure does not build.
Is there some other way?

I don't know the answer to your problem, but I do know looking up Wikipedia is not the way to find it. Try doing some sort of literature search to find the methodology for converting the β-Ga2O3 to α-Ga2O3.

I'm beginning to suspect that the only possible α-Ga2O3 to β-Ga2O3 transition, because β-modification is very stable...
