Iron(II) oxide

2+

Hence the oxidation number of Fe in Fe3O4 are +2 and +3 respectively.

Using atomic weights of Fe = 55.845(2) and O = 15.9994(3), we obtain molecular weights for Fe2O3 = 159.688 and 2(FeO) = 143.689. This gives a conversion factor of 159.688 / 143.689 = 1.1113.

FeO

The compound formed when iron reacts in the air with oxygen is ferric oxide. It has a reddish-brown hue and is also known as the hematite and rust mineral. Ferrous oxide is black and is referred to as the mineral wustite.

Iron(III) Oxide Trihydrate. Ferric Oxide Trihydrate. Fe2O3.3H2O.

Hematite is identified by its non-metallic or metallic luster and its red to red-brown streak. Hematite is identified by its non-metallic or metallic luster and its red to red-brown streak. Its hardness is 1.5 to 5.5.

Hematite has an almost steely quality and feel to it which means that intellectually speaking, you always feel as though you have a solid footing.

Hematite and magnetite are by far the most common types of ore. Pure magnetite contains 72.4 percent iron, hematite 69.9 percent, limonite 59.8 percent, and siderite 48.2 percent, but, since these minerals never occur alone, the metal content of real ores is lower.

The Hematite should be a bit red below the surface or the powdered Hematite should be reddish in a real gemstone. The same idea works with a streak test. Scrape a piece of Hematite across some unglazed porcelain or some black sandpaper and it should leave a red or brown streak.

Hematite Stone Benefits

The key difference between magnetite and hematite is that the iron in magnetite is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state. Magnetite and hematite are minerals of iron. Both have iron in different oxidation states, and they are in the forms of iron oxides.

Magnetite is sometimes found in large quantities in beach sand. Such black sands (mineral sands or iron sands) are found in various places, such as Lung Kwu Tan of Hong Kong; California, United States; and the west coast of the North Island of New Zealand.

Hemalyke, hematin and similar synthetic stones do not usually contain any real hematite, but can be polished to resemble natural hematite and have a strong magnetic field.

The problem with magnetite is that it’s toxic. It causes oxidative stress, disrupting normal cellular function and contributing to the creation of destructive free radicals—unstable molecules that can damage other important molecules.

Summary: Prolonged exposure to low-level magnetic fields, similar to those emitted by such common household devices as blow dryers, electric blankets and razors, can damage brain cell DNA, according to researchers in the University of Washington’s Department of Bioengineering.

These magnetic particles have been linked to Alzheimer’s disease, and are thought to generate reactive compounds that can kill nerve cells. We have known for some time that there are magnetite particles in our brains, but until now, it was thought that they came from natural sources.

The scientists found that most parts of the brain could be magnetized; in other words, these areas all contained magnetic particles. But in all seven brains, the brain stem and the cerebellum had greater magnetism than the higher-up cerebral cortex.

By adding one magnet on to the other, e.g. stacking, the stacked magnets will work as one bigger magnet and will exert a greater magnetic performance. As more magnets are stacked together, the strength will increase until the length of the stack is equal to the diameter.

While it’s generally safe for most people to wear low-intensity static magnets, it’s not a good idea to have magnetic field therapy if you: Use a pacemaker.

Restoration of cellular magnetic balance. Migration of calcium ions is accelerated to help heal bones and nerve tissues. Circulation is enhanced since biomagnets are attracted to the iron in blood and this increase in blood flow helps healing.
