DEFINITION

Classification: 505/781

Noble metal (i.e., Ag, Au, Os, Ir, Pt, Ru, Rh, Pd) or chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co) or nickel (Ni) - [e.g., YBa2Cu(3-x)Fe(x)O(y)]:

(under subclass 780) Material containing a noble metal i.e., Silver (Ag), Gold (Au), Osmium (Os), Iridium (Ir), Platinum (Pt), Ruthenium (Ru), Rhodium (Rh) or Palladium (Pd) or one or more of the Iron Group metals i.e., Chromium (Cr), Manganese (Mn), Iron (Fe), Cobalt (Co) or Nickel (Ni).
