How do I determine if a Metal Fluoride is soluble in liquid Gallium and under what conditions the Metal Fluoride will stay in solution in the liquid Gallium?
I am involved in a project that is testing approaches to using CVD to form a graphene layer on liquid Gallium. Fluorine has been used in the process to disassociate methane into carbon and hydrogen and to speed the deposition of carbon. In our project, we are using Acetelyne.
We want to try a different approach of adding a small amount of Fluorine into the liquid gallium itself. With the energies involved it should allow a small amount of F to interact with the process at the surface. I am familiar with all the other aspects but I have never dealt with trying to dope liquid gallium with Fluorine.
My thought was to add a Metal Flouride to liquid Gallium at an appropriate temp/pressure to have it dissolve in the liquid metal. The resulting liquid would be used as a base for deposition at temperatures between 200c to 700c at varying plasma energy levels.
I am considering a few options; SnF2, GaF3, and NaF
Gallium Fluoride would be the best for my application, but the other two are easier to obtain and should still work.
This is going to be < 1 milligram of Metalic Fluoride compound per gram of Gallium and never more than 10 grams of the resulting product at any time.
