Dispersion of nano-alumina in a resin or solvent system

Dispersion of sol-derived nano-alumina in an organic solvent mixture containing a 1,2-diol with simple agitation. A thixotropic solution is obtained at 20% alumina in ethylene glycol, while a low viscosity (<100 cps) solution is possible for a 20% alumina in (1:1, N-methylpyrrolidone-ethylene glycol) solution.
