ABSTRACT:
A method for preparing a suspension for coating a substrate with particles which includes determining a pH range in which the heterostability ratio of the substrate and the particles: ##EQU1## is less than 10.sup.10, the homostability ratio of the substrate: ##EQU2## is greater than 10.sup.10, and the homostability ratio of the particles: ##EQU3## is greater than 10.sup.10, wherein a.sub.1 is the radius of the substrate, a.sub.2 is the radius of the particles, V.sub.T is the total potential energy of the interaction between component i and component j, wherein i and j are the consecutive subscripts of the stability ratio being considered, T is temperature, k is Boltzmann's constant, and r is distance which varies from (a.sub.i +a.sub.j) to infinity. The suspension is useful for coating the substrate with the suspended particles by exposing the substrate to the suspension.
