Hematite
Hematite,also spelled as haematite, is a common iron oxide compound with the formula, Fe2O3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2O 3. It has the same crystal structure as corundum (Al 2O 3) and ilmenite (FeTiO 3). With this it forms a complete solid solution at temperatures above 950 °C (1

28/05/2015 Watermedia effects cling well to this metallic texture! Hematite was used historically as a pigment in cave paintings, ancient Greece, the Renaissance and beyond, though it was mainly used for its red component! With each Natural History museum I visit, I'm always on the lookout for what their Hematite Ore samples look like.

Mineral Resource of the Month: Iron Oxide Pigments EARTH
20/06/2018 Natural pigments are derived from several iron oxide minerals: Red pigments are derived from hematite. Yellow and brown pigments — ochres, sierras and umbers — are derived from limonite. Magnetite provides a black iron oxide pigment. Micaceous iron oxide is a special form of hematite that occurs in thin metallic gray platelets or flakes.

Preparation of monodispersed micaceous iron oxide pigment
15/02/2011 Monodispersed micaceous iron oxide (MIO) pigment is prepared from pyrite cinders. SEM image (Fig. a, 11) reveals that the obtained MIO particles are uniform flakes, and their mean particle size is ~ 7.0 μm with an aspect ratio of ~ 7.0.XRD pattern (Fig. b) demonstrates that the synthesized MIO is well crystallized and coincides with hematite structure.

Hematite: Meaning, Healing Properties and Powers
Hematite is a grounding stone that is mostly used for protection and stability. The word "hematite" is derived from a Greek word that means "blood." As a result, it is known as the "bloodstone" and has been employed as a talisman against excessive blood flow. Hematite is a kind of iron ore that is made up of iron oxide crystals.

MIO is processed, Micaceous hematite ore with a metallic lustre or sparkle that can be easily seen with the naked eye. Like the other forms of iron oxide, MIO is a chemically inert material and is insoluble in water, organic solvents, and alkalis. It is un-reactive to most of the chemicals and is heat stable up to it's melting point of over 1,000 C (2,700 F).
