Hematite: The mineral hematite information and pictures

Hematite was largely used in the past as a red and brown pigment, although nowadays cheaper sources have been substituted. Well formed Hematite crystals are popular among mineral collectors, and tumbled, highly lustrous Hematite from Brazil makes a very popular, inexpensive specimen for amateur collectors. Hematite is also used as a minor gemstone.

Magnetic Hematite: Mineral information, data and localities.

Please note that the name 'hematite' is quite misleading, as this is NOT a natural stone. Investigation of one item offered for sale as 'magnetic hematite' showed it was composed of a ceramic barium-strontium ferrite magnet: (Ba,Sr)Fe 12 O 19 that has the magnetoplumbite structure. The average grain size of the ceramic is 5-10 microns, and the ...

Hematite - Wikipedia

Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe 2 O 3 and is widespread in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3. It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3), with which it forms a complete solid solution at temperatures above 950 °C ...

Hematite – Virtual Museum of Molecules and Minerals

Hematite Mineral Description. Hematite is an iron-oxide mineral of the Oxides and Hydroxides group, with structural formula [alpha-Fe 2 O 3].The structure is similar to that of corundum, and consists essentially of a dense arrangement of Fe 3+ ions in octahedral coordination with oxygen atoms in hexagonal closest-packing. The structure can also be described as the stacking of sheets of ...

Hematite | Physical - Optical Properties, Occurrence, Uses

Hematite is dense and hard, it is the most important ore of iron because of its high iron content and its abundance. The mineral occurs in various habits: steel-gray crystals and coarse-grained varieties with a brilliant metallic luster are known as specular hematite; thin, scaly forms make up micaceous hematite; and crystals in petal-like arrangements are called iron roses. It also occurs as ...
