Particle surface treatment |
| abstract |
A method of treating particulate titanium dioxide includes providing the particulate titanium dioxide which includes a crystal structure and then treating the particulate titanium dioxide with a coating agent that is an alkylphosphonic acid or an ester thereof, and steam micronizing the particulate titanium dioxide with a steam micronizer so that a vapor exit temperature from the steam micronizer is 150° C. or higher, so as to obtain a micronized particulate titanium dioxide which includes the coating agent at an outer surface. The particulate titanium dioxide includes an aluminum oxide coating and/or includes within the crystal structure aluminum oxide in a molar excess of an amount required to compensate any Nb2O5 in the crystal structure. The alkylphosphonic acid includes a C6-C22 alkyl group. |
