Abstract
Disclosed is a method of producing metal oxides, comprising electrodepositing a metal oxide from an electrolyte solution onto a substrate to coat at least a portion of the substrate, whereby metal oxide seed particles are released into the solution, and precipitating metal oxide particles from the solution. The precipitated metal oxide particles have a maximum particle size of less than 1 micron.

A method of producing metal oxide particles comprising:
- electrodepositing an oxide of a metal from an electrolyte solution onto a substrate to coat at least a portion of the substrate, whereby seed particles of the metal oxide are released into the solution;
- and
- precipitating metal oxide particles from the solution.
A pigment composition comprising discrete particles of rutile TiO2, wherein said particles are produced by electrolytic precipitation from an electrolyte composition comprising TiOCl2.
