DEFINITION

Classification: 502/300

Metal, metal oxide or metal hydroxide:

(under subclass 100) Composition which contains a metal* either as the free element or combined with oxygen or with hydrogen and oxygen.

(1) Note. A metal metallate is considered to be a mixture of a metal oxide with a metal or other metal oxide. For example, a composition comprising nickel chromate is considered to include nickel oxide and chromium oxide.

(2) Note. This and indented subclasses do not provide for a metal hydride, per se, unless mixed with a metal, or oxide or hydroxide thereof.

(3) Note. See Glossary under metal for synonyms or archaic terms for elements provided in this or an indented subclass.

(4) Note. This subclass is residual for a catalyst composition comprising an actinic or group VII (other than manganese) metal, oxide or hydroxide not containing a metal provided for in an indent.
