Hematite (/ ˈ h iː m ə ˌ t aɪ t, ˈ h ɛ m ə-/), also spelled as haematite, is a common iron oxide compound with the formula, Fe 2 O 3 and is widely found in rocks and soils. [6] 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 ...
It can be prepared by reduction of hematite by carbon, [clarification needed] pyrolysis of iron(III) chloride solution, or thermal decomposition of iron(III) sulfate. [ 13 ] The epsilon (ε) phase is rhombic, and shows properties intermediate between alpha and gamma, and may have useful magnetic properties applicable for purposes such as high ...

Fe 3 O 4: Iron(II,III) oxide, magnetite; Fe 4 O 5 [2] Fe 5 O 6 [3] Fe 5 O 7 [4] Fe 25 O 32 [4] Fe 13 O 19 [5] Oxides of Fe III. Fe 2 O 3: iron(III) oxide. α ...
Hematine ring. Hematine (also magnetic hematite, hemalyke or hemalike) is an artificial magnetic material. [1] Hematine is widely used in jewelry. [citation needed]Although it is claimed by many that it is made from ground hematite or iron oxide mixed with a resin, analysis (of one object) has demonstrated it to be an entirely artificial compound, a barium-strontium ferrite.
Excessive hematite can weaken the pellet structure during reduction, leading to the pellets breaking down into dust under the weight of stacked charges. This is due to the fact that a high hematite content can cause the pellets to disintegrate, compromising their integrity and usability in the reduction process.
The "classic" bloodstone is translucent to opaque green chalcedony and red jasper that contains inclusions of hematite. The red jasper may resemble spots of blood , hence the name bloodstone . Other colors of chalcedony may also occur in Indian bloodstone, such as white, yellow, or blue.

Magnetite has been important in understanding the conditions under which rocks form. Magnetite reacts with oxygen to produce hematite, and the mineral pair forms a buffer that can control how oxidizing its environment is (the oxygen fugacity). This buffer is known as the hematite-magnetite or HM buffer.
