Manganese(VII) oxide (manganese heptoxide) is an inorganic compound with the formula Mn 2 O 7 Manganese heptoxide is a volatile liquid with an oily consistency. It is a highly reactive and powerful oxidizer that reacts explosively with nearly any organic compound .
Cadmium permanganate can also be produced by reacting manganese heptoxide with cadmium oxide [2] or cadmium hydroxide. [3] Properties.
Permanganic acid has also been prepared through the reaction of hydrofluorosilicic acid with potassium permanganate, [4] through electrolysis, and through hydrolysis of manganese heptoxide, though the last route often results in explosions. [5] Crystalline permanganic acid has been prepared at low temperatures as the dihydrate, HMnO 4 ·2H 2 O. [3]
Manganese may also form mixed oxides with other metals : Bixbyite, (Fe III,Mn III) 2 O 3, a manganese(III) iron(III) oxide mineral; Jacobsite, Mn II Fe III 2 O 4, a manganese(II) iron(III) oxide mineral; Columbite, (Fe II,Mn II)Nb 2 O 6, a niobate of iron(II) and manganese(II) Tantalite, (Fe II,Mn II)Ta 2 O 6, a tantalum(V) mineral group close ...
Ammonium permanganate decomposes explosively to manganese dioxide, nitrogen, and water: [2] 2 NH 4 MnO 4 → 2 MnO 2 + N 2 + 4 H 2 O. Ammonium permanganate decomposes slowly in storage even at normal temperatures. A sample stored for 3 months was only 96% pure, after 6 months it assumed color of iodine and had strong smell of nitrogen oxides.
Brisance is important in determining the effectiveness of an explosion in fragmenting shells, bomb casings, and grenades. The rapidity with which an explosive reaches its peak pressure ( power ) is a measure of its brisance.

4 and leaving a residue of purified manganese dioxide. [8] These two steps can be summarized as: MnO 2 + N 2 O 4 ⇌ Mn(NO 3) 2. In another process, manganese dioxide is carbothermically reduced to manganese(II) oxide which is dissolved in sulfuric acid. The filtered solution is treated with ammonium carbonate to precipitate MnCO 3.
