An important iron ore. The chemical composition is iron oxide. Semi-metallic to metallic luster, colors are reddish brown, steel gray, iron black and so on. The stripes are cherry red and the Mohs hardness is 5 _ 5 ~ 6 _ 5. Aggregates are flaky, kidney-shaped, massive or earthy. It is widely distributed. The iron content can reach 69_9%, which is the main raw material for ironmaking. It can also be used as pigment and abrasive.
Second, the national language dictionary
A mineral. The composition is iron oxide, the crystal belongs to hexagonal system, often in plate, block or grape shape, red and black, which is the main iron ore. In addition to ironmaking, it can also be used as a grinding material for pigments, lenses, etc. English hematite (Redionore), Ferricoxidedefe2O3 German H_matit French hématite.
Third, the network interpretation
Hematite Hematite is a hexagonal oxide mineral, and its chemical composition is Fe2O3. It is isomorphic with maghemite (γ-Fe2O3) isomorphic with equiaxed crystal system. Single crystals are usually rhombic and tabular. Aggregates have various shapes, such as flaky, scaly (crystalline), granular, oolitic, kidney-shaped, earthy, dense block and so on. The color is reddish brown, steel gray to iron black, and the stripes are cherry red. Metallic to semi-metallic luster. Mohs hardness is 5.5 ~ 6.5, and specific gravity is 4.9 ~ 5.3. The flaky hematite aggregate with iron black and metallic luster is called specularite. The scale-like hematite aggregate with gray and metallic luster is called mica hematite, which was called "Yunzi Iron" in ancient China. The reddish-brown and dull ochre is called "ochre" in ancient China, and "ochre" generally refers to hematite. Oolitic or renal hematite is called oolitic or renal hematite. Hematite is an iron mineral widely distributed in nature, which is an important raw material for ironmaking and can also be used as a red pigment. 2065438+071October 27 17 The list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization was preliminarily sorted out for reference. Hematite (underground) belongs to a class of carcinogens, and hematite belongs to a class of carcinogens.
