Is Hematite Magnetic? Techiescientist

Apr 24, 2021 The chemical formula of hematite is Fe2O3 whereas the electronic configuration of iron and oxygen are: Iron: 1s22s22p63s23p63d64s2 Oxygen: 1s22s22p4. From the electronic configurations of iron and oxygen, it can be figured out there will be a deficiency of paired electrons which promotes paramagnetic behavior in hematite.

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 (1,740 °F). Hematite naturally occurs in black to steel or silver-gray, brown to reddish-brown, or red colors. It is mined

Hematite an overview ScienceDirect Topics

Iron is the 4th most abundant element in the Earth's crust and it exists mostly as an oxide because it is easily oxidized in air. Iron has 16 oxides and among these, hematite is the oldest known. Hematite is a red-brown solid that is extremely stable under ambient conditions. It is often the end-product of all other iron oxide transformations.
