Silicon Carbide Slurries/Suspension Media

I am currently looking into a new project of suspending silicon carbide grit (45% by weight) into a 500 solvent neutral base oil. The product has to be water washable as well. I have tried bentonite clay to help stabilize the grit suspension, but to no avail. The grit either drops out, the slurry gels up, there is too much oil bleed or the grit packs hard. Has anyone got any tips on how to stabilize the SiC slurries?

You may get a uniform dispersion of your powders if you coat your particles with thin layer of solvent compatible compound. General scientific methods are there. However, for your specific system, optimization of the experimental parameters for uniform coating would be needed before getting product with desired properties.
