What is the main component of magnetite?
Half metallic to metallic luster. Opacity. No cleavage, sometimes visible "{111} split, often as titanium magnetite in inclusions fe2tio4, titanium magnetite micro shape due to arrangement in {111} direction. Sexual fragility. Hardness 5.5~6. Relative density 4.9~5.2. Strong magnetic, Curie point (Tc) 578. The Curie point is a thermo magnetic effect of magnetic minerals, which transforms the magnetic or diamagnetic material into the critical temperature of paramagnetic material.
Magnetite Magnetite is an oxide mineral, magnetite ore. Equiaxed system. The crystal has eight sides and twelve faces. The surface of the crystal has stripes. Most of them are granules and lumps. Iron black, or a Dark Indigo color. Streak black, semi metallic luster. Opacity. No cleavage. Uneven fracture. Hardness 5.5 ~ 6.5. The density of 5.16 ~ 5.18g/cm fand. Strongly magnetic. Sexual fragility. Odorless, tasteless. Often occurring in igneous rocks and metamorphic rocks. Beach sand often exist. Distribution of Shandong, Hebei, Henan, Liaoning, Heilongjiang, Inner Mongolia, Hubei, Yunnan, Anhui, Guangdong, Sichuan, Shanxi, Jiangsu, and Hong kong.
The main component of magnetite is: FeO 31.03%, Fe O accounted for 68.96%.
