I'm trying to get some proof of concept for in situ Raman monitoring of metal oxide synthesis using a salt flux. I really need a simple system with fairly common oxides, so I can get the funds to do the ones I want. Any ideas would be appreciated.
Dear James Burgess, the question is a bit unclear. Are you looking for funds to pursue this research, or for molten salts. If it is this later, just search using the keyword ' ionic liquids in metal oxides synthesis '. My Regards

Definitely with molten salt synthesis one has observed that the calcination temperatures are lowered to obtain the final product, and normally involves reaction between two different binary oxides.
Since you plan to use Raman spectroscopy to understand the reactions insitu, I would suggest a system which has a low calcination/sintering temperature, because it will then be convenient to use the Raman probe.(normally below 600 deg C).
- You can try SrO and MoO3 to form SrMoO4 (strontium molybdate), a very important laser material for photonics.
- Also try PbO and TiO2 to form PbTiO3.
-Bi2O3 and TiO2 to from Bi4TiO12
-The best way is to see which multi-component oxide system requires a lvery low calcination/sintering temperature by the normal solid state reaction technique, and hen apply the molten sal synthesis technique to see if the calcination temperatures re reduced to give the final single phase reacted product., and use such a system to study insitu by Raman spectroscopy which is normally available for use
