A method of reducing the agglomeration of inorganic powdered material, the method comprising: (a) providing an inorganic powdered material comprising ceramic particles; (b) coating the ceramic particles with a solution containing from 0.05-0.5 wt. % of a polysiloxanol oligomer of a trialkoxysiloxane monomer having the structure Si(OR') 3 wherein R' represents a C 1 -C 4 alkoxy group selected from the group consisting of methyl, ethyl, isopropyl and n-butyl and wherein the oligomer has chains having a number average distribution with a number average degree of polymerization X n in the range above 2 but below the gel point; and (c) drying the inorganic powdered material. |
