Manganese violet is the inorganic compound with the formula NH 4 MnP 2 O 7. [1] As implied by its name and composition, it is a purple, inorganic pigment. [2] Because it is often impure, the pigment's hue is varied. [3]
Ultramarine violet (PV15): a synthetic or naturally occurring sulfur containing silicate mineral. Copper pigments. Han purple: BaCuSi 2 O 6. Cobalt pigments. Cobalt violet (PV14): Co 3 (PO 4) 2. Manganese pigments. Manganese violet: NH 4 MnP 2 O 7 (PV16) manganic ammonium pyrophosphate. [2]
Purple/violet robes were particularly worn by students of divinity. ... Manganese violet was a stronger color than cobalt violet, and replaced it on the market.
Purpurite is a manganese phosphate mineral with the formula MnPO 4, with varying amounts of iron depending upon its source. It occurs in color ranges from brownish black via purple and violet to dark red. [3] Purpurite forms a series with the iron-bearing endmember heterosite, FePO 4. [4]
violet yellow 424–491 ... purple Titanium(IV) ... Manganese: violet (hot and cold) colorless (hot and cold) Molybdenum: colorless: yellow or brown (hot)
Manganese dioxide, which is black, is used to remove the green color from the glass; in a very slow process this is converted to sodium permanganate, a dark purple compound. In New England some houses built more than 300 years ago have window glass which is lightly tinted violet because of this chemical change, and such glass panes are prized ...
Manganese in oxidation state +7 is represented by salts of the intensely purple permanganate anion MnO − 4. Potassium permanganate is a commonly used laboratory reagent because of its oxidizing properties; it is used as a topical medicine (for example, in the treatment of fish diseases).
This color, electric purple, is precisely halfway between violet and magenta and thus fits the artistic definition of purple. [ 15 ] Using additive colors such as those on computer screens, it is possible to create a much brighter purple than with pigments where the mixing subtracts frequencies from the component primary colors.
