DEFINITION

Classification: 526/95

(under subclass 90) Subject matter wherein the specified material contains a transition metal atom as part of a binary compound solely composed of a single transition metal and oxygen.

(1) Note. Included herein are supports for active ingredients wherein the support may be an oxide of a transition metal (e.g., thoria, titania, etc.).

(2) Note. Excluded from this subclass are the peroxides of a transition metal.

(3) Note. This subclass includes reaction products or reaction mixtures of transition metal oxides wherein the surface of the transition metal oxide may be modified (e.g., TiO2 chemically bonded to TiCl4 on its surface) but wherein the material is still regarded as being in oxide form.
