“…The reaction of elementary silver or Ag 2 O with MnO, Mn 3 O 4 , and Mn 2 O 3 in the presence of oxygen yielded various silver manganese oxides with the {Ag x MnO 2 } n general formula like AgMnO 2 ( x = 1; n = 1), {Ag 2 MnO 2 } ( x = 2; n = 1), or Hollandite-type Ag 1.8 Mn 8 O 16 ( x = 0.225; n = 8). Decomposition or reduction of AgMnO 4 (1:1 Ag/Mn stoichiometry) with H 2 , H 2 O 2 , CO, or metallic silver resulted in mixed oxides with the {AgMnO x } ( x = 2–3) composition. The composition of compound 1 and AgMnO 4 (Ag:Mn = 1:1) predetermined the stoichiometry of the single-phase decomposition product.…”

“…Upon further heating, the finely divided silver easily reacted with manganese oxides (MnO, Mn 2 O 3 , and Mn 3 O 4 ). The reaction of α-MnO 2 does not give silver–manganese oxides, but γ- and ρ-MnO 2 formed from the decomposition of manganese­(II) nitrate react with metallic silver. The reaction, during which the elementary silver completely disappeared, proceeded in an air atmosphere even at 573 K (Figure ).…”
