DEFINITION

Classification: 75/234

Oxygen (O) associated with more than one metal:

(under subclass 232) Composition containing oxides of more than one metal, or containing the oxide of plural metals, e.g., a metal silicate, etc.

(1) Note. Where all of the metals with which Oxygen (O) is associated are selected from Aluminum (Al), Beryllium (Be), Magnesium (Mg), Alkaline earth metal, Scandium (Sc), Yttrium (Y), Lanthanide metal, Actinide metal, Titanium (Ti), Zirconium (Zr), or Hafnium (Hf) placement of the patent is in subclass 235.

(2) Note. Included herein are those nonmetal additives such as clay, slag, or spinels, which are a combination of divalent metal oxide and a trivalent metal oxide having the formula MO.M'2O3 or MM'2O4, not provided for in subclass 235.
