n.
Hydrous sesquioxide of iron, an important ore of iron, occurring in stalactitic, mammillary, or earthy forms, of a dark brown color, and yellowish brown powder. It includes bog iron. Also called brown hematite.
n.
An element which is combined with a metal, thus forming an ore. Thus, in galena, or lead ore, sulphur is a mineralizer; in hematite, oxygen is a mineralizer.
n.
Same as Hematite.
a.
Hematite or specular iron ore; -- prob. so called in allusion to its feeble magnetism, as compared with magnetite.
n.
A impure earthy ore of iron or a ferruginous clay, usually red (hematite) or yellow (limonite), -- used as a pigment in making paints, etc. The name is also applied to clays of other colors.
a.
Of or pertaining to hematite.
a.
Of or pertaining to hematite, or resembling it.
n.
An important ore of iron, the sesquioxide, so called because of the red color of the powder. It occurs in splendent rhombohedral crystals, and in massive and earthy forms; -- the last called red ocher. Called also specular iron, oligist iron, rhombohedral iron ore, and bloodstone. See Brown hematite, under Brown.
n.
The most common and most useful metallic element, being of almost universal occurrence, usually in the form of an oxide (as hematite, magnetite, etc.), or a hydrous oxide (as limonite, turgite, etc.). It is reduced on an enormous scale in three principal forms; viz., cast iron, steel, and wrought iron. Iron usually appears dark brown, from oxidation or impurity, but when pure, or on a fresh surface, is a gray or white metal. It is easily oxidized (rusted) by moisture, and is attacked by many corrosive agents. Symbol Fe (Latin Ferrum). Atomic weight 55.9. Specific gravity, pure iron, 7.86; cast iron, 7.1. In magnetic properties, it is superior to all other substances.
n.
Hematite, an ore of iron yielding a blood red powder or "streak."
