ABSTRACT:
A metal oxide is treated with an organophosphate, such as a trialkyl phosphate, to convert the oxide to the corresponding phosphate. The metal in the oxide can be a transition metal, such as iron, and the trialkyl phosphate preferably contains from one to about four carbon atoms in each alkyl group. The treatment can be conducted at an elevated temperature of about 250.degree. C. or greater.
