Manganese(II) phosphate Manganese(II) phosphate Manganese(II) phosphate is an inorganic compound with the chemical formula Mn(PO). It is a rarely studied species, in contrast to the related lithium manganese phosphate, which has been investigated as a battery cathode. Manganese phosphates often combine with iron phosphates through paragenesis. In the process of paragenesis, each mineral affects the manner in which the other is crystallized. The minerals combine in isomorphic series, meaning that they crystallize in similar forms, producing a sequence of solids. Some examples of “isomorphic series” formed by Mn and Fe include heterosite (Fe,Mn)PO, purpurite (Mn,Fe)PO, and triplite (Mn,Fe)PO. The immersion method is
Manganese modern times as pyrolusite or manganese dioxide. Neither this mineral nor elemental manganese is magnetic. In the 16th century, manganese dioxide was called "manganesum" (note the two Ns instead of one) by glassmakers, possibly as a corruption and concatenation of two words, since alchemists and glassmakers eventually had to differentiate a "magnesia negra" (the black ore) from "magnesia alba" (a white ore, also from Magnesia, also useful in glassmaking). Michele Mercati called magnesia negra "manganesa", and finally the metal isolated from it became known as "manganese" (German: "Mangan"). The name "magnesia" eventually was then used to refer only to the
