The method involves reacting A and B cations to yield a pyrochlore oxide by precipitation of A and B cations in a liquid medium having a pH which is equal to or greater than 4.5, but less than 13.5, in the presence of an oxygen source at a temperature below about 200.degree. C. for a time sufficient for reaction to occur. In those instances in which amorphous reaction products are obtained, these amorphous reaction products are subsequently heat treated at a temperature of about 200.degree. C. to about 600.degree. C. for a time sufficient to convert amorphous reaction products to crystalline pyrochlore(s).
