In a reactor, the plutonium would be combined with uranium in a form called mixed oxide, and abbreviated as MOx.

The limelight was fading, but the white hot glow of the mixed oxides of thorium and cerium was there to take its place.

It may also show a mixed oxide, FlO, analogous to PbO.

So far, most fast neutron reactors have used either MOX (mixed oxide) or metal alloy fuel.

There are many mixed oxides containing aluminium where there are no discrete or polymeric aluminate ions.

It is a mixed oxide of lead, scandium, and tantalum.

Dehydrating metal salts containing this anion yields mixed oxides.

An extensive series of non-stoichiometric mixed oxides exists.

MOX, or mixed oxide, fuel is the new plutonium-based fuel that the largest utilities had planned to start using late last year.

It is sometimes called a "mixed oxide."
