Abstract
Dispersions of colloidal siliceous particles, preferably silica, may be prepared in organic liquids by means of a synergistic mixture of dispersing agents comprising a phosphorus oxy-acid derivatives and a long-chain amine. Dispersions containing a high weight fraction of siliceous solids are possible having a lower viscosity than is normally achieved.
