ABSTRACT:
Novel rhenium oxides of the formulas MReO.sub.4 and M'.sub.2 ReO.sub.6, where M is Mg, Zn, Mn, Al, Ga, Fe, Co, or Ni and M' is Cr or Fe, are prepared by heating powder mixtures containing precursor oxides with or without some of the metals selected to give the proper stoichiometry, under a pressure of at least 25 kbars. The new oxides are useful in electrical elements, e.g., resistors.
