4.Altough an increased incidence of lung cancer has been observed among hematite miners exposed to iron oxide, presumably as a result of concomitant radon gas exposure, there is no evidence that iron oxide alone is carcinogenic to man or animalsFe3O4, Black Iron Oxide, BIO, Magnetite Powder, IronII,III Oxide MaterialsGeneral Iron

5.Magnetite is a black, opaque, magnetic mineral that leaves a black streak when rubbed across a hard rough surface It is one of the most abundant metal oxides, and its crystal structure contains both the ferrous Fe+2 and ferric Fe+3 forms of iron ions

6.Infrared and Raman spectroscopic studies on iron oxide magneticIron oxide magnetic nano particles have been prepared in aqueousmagnetite by IR spectroscopy revealed that the conversion to hematite began by 300 o

8.What is the difference between Fe2O3 and Fe3O4 Fe2O3 can be attracted to a strong, external magnetic field whereas Fe3O4 can be attracted to even a weakFe 3 O 4 has a dark black colorFe 2 O 3: Fe 2 O 3 is ironIII oxide, also known as hematite Fe 3 O 4: Fe 3 O 4 is ironII,III oxide, also known as magnetite Appearance Fe 2

9.Crystals of Hematite are considered rare and are sought after by collectors as are fine Kidney Ore specimens Hematite is sometimes used in jewelry, either as black reflective stones or as a jewelry piece itself such as a ring Some jewelry is marketed as "magnetic hematite" I believe that is more likely another iron oxide, magnetite

10.Hematite is a magnetic material, although its magnetism is weaker if compared to that of magnetite Hematite stones are very compact and relatively heavy They can range in color from black to reddishbrown, but by far the most dominant is the silvergray metallic color

11. The bandgap of hematite is 20 to 22 eV which makes it useful in applications that involve visible light absorption [13,14] Magnetite has unique electric and magnetic properties because its intrinsic crystal structure allows electrons to be transferred between

12.Magnetite, also called lodestone, or magnetic iron ore, iron oxide mineral FeFe 2 O 4, or Fe 3 O 4 that is the chief member of one of the series of the spinel qv groupMinerals in this series form black to brownish, metallic, moderately hard octahedrons and masses in igneous and metamorphic rocks and in granite pegmatites, stony meteorites, and hightemperature sulfide veins

14.Like nearly all commerciallyavailable hematite beads, our semiprecious beads are cut from a simulated material that is virtually identical to real hematite This manmade variety has the same chemical composition as genuine hematite iron oxide, and actual hematite is used in its creation

15.Magnetite is a natural iron oxide magnet, hence the name, giving it a very nice distinguishing characteristic Magnetite is the most magnetic of all the minerals on Earth Magnetite is a member of the spinel group which has the standard formula AB2O4
