A mixed oxide is an oxide of more than one chemical element. An oxide is a Chemical compound containing at least one Oxygen atom as well as at least one other element A chemical element is a type of Atom that is distinguished by its Atomic number; that is by the number of Protons in its nucleus.
See category for a list. Also see MOX fuel for mixed-oxide nuclear fuel. Mixed oxide, or MOX fuel, is a blend of oxides of Plutonium and Natural uranium, Reprocessed uranium, or Depleted uranium which behaves
In some cases, a mixed oxide X Y oxide can be contrasted with a compound X Yate.
In most cases, common sense can prevail.
For example, the compound sodium nitrate is not described as 'sodium nitrogen oxide'; even less so, would it be called 'nitrogen sodate'. Sodium nitrate is the Chemical compound with the formula NaNO3 With this, we have some common sense, that the compound is a nitrate, not a 'sodate', and not even a mixed oxide. In Inorganic chemistry, a nitrate is a salt of Nitric acid with an Ion composed of one Nitrogen and three Oxygen atoms
In some cases, the conclusion is not so obvious. For example, some compounds are called 'titanates'; are these 'titanates', or maybe X titanium oxides? In this case, the result depends on some knowledge of structure: in general, Xates have the Xate ion; a mixed oxide will not have such. An ion is an Atom or Molecule which has lost or gained one or more Valence electrons giving it a positive or negative electrical charge
