Triboelectric effect - Wikipedia

The triboelectric effect (also known as triboelectric charging) is a type of contact electrification on which certain materials become electrically charged after they are separated from a different material with which they were in contact. Rubbing the two materials with each other increases the contact between their surfaces, and hence the triboelectric effect.

Manganese Ferroalloys Technology - ScienceDirect

Manganese forms several oxides, of which only monoxide (MnO) is stable at high temperatures. The unstable higher oxides MnO 2, Mn 2 O 3, and Mn 3 O 4 predominate in manganese ores. Higher manganese oxides such as Mn 2 O 7 are very unstable and easily decompose even at room temperatures. MnO 2 and Mn 2 O 3 dissociate in solid state to lower oxides when heated. Figure 7.1 …
