I am trying to make a reasonably stable GaN suspension using its powder which has an average flake size of 200 nm. What are the best solvents for this purpose?
The surface of gallium nitride adsorbs well the anions of chlorine, bromine, iodine from the aqueous solution. Therefore, water with sodium chloride can be used as the dispersant. It is better to add a neutral thickener of polyethylene oxide to the solution.

Thank you very much, Dr. Mirgorod. Your suggestion seems to match with my experimental observations.
Dear Yuri,
Thanks to remind me the rule, but I want to challenge your suggestion for NaCl as I am sure LiCl and SbCl3 work much better than NaCl to get a well suspension. Just google and find some text doesn't mean your answer is correct. We are here to help others in the based way based on our experience and observation in our own research!!
