Definitions
from The American Heritage® Dictionary of the English Language, 5th Edition.
- noun A steel-gray to black mineral, MnO(OH), found in North America and Europe; manganese oxide.
from The Century Dictionary.
- noun A hydrated oxid of manganese occurring in orthorhombic crystals of a steel-gray or iron-black color and brilliant luster, also in masses having a columnar structure. It is often altered, by loss of water, to pyrolusite. Also called
gray manganese ore . - noun A substance which may be viewed as a compound of manganese dioxid with the monoxid of a more basic or electropositive metal.

- noun (Min.) One of the oxides of manganese; -- called also
gray manganese ore . It occurs in brilliant steel-gray or iron-black crystals, also massive. - noun (Chem.) A compound of manganese dioxide with a metallic oxide; so called as though derived from the hypothetical
manganous acid.
