What is "Magnetic Hematite"?"Magnetic Hematite" or "Hematine" is a composite material derived from Natural Hematite (iron oxide-Fe2O3), Magnetite (iron oxide- Fe3O4) and small amounts of other natural minerals such as copper, titanium and aluminum. This composite material can be intensely and permanently magnetized. (Natural hematite cannot be magnetized.)"Magnetic Hematite" is produced by heating a powdered mixture of the above ground-up natural materials (hematite, magnetite, copper etc.) through a process called "Powder Metallurgy". Powder Metallurgy* is the process of blending fine powdered minerals, pressing them into a desired shape or form (hematite beads, pendants, etc), and then heating the resulting shapes in a controlled atmosphere to bond the material by a heating process called "sintering" (high temperature firing). The shaped beads, pendants, etc, are cooled and then re-sintered (reheated) inside an external electromagnetic field to achieve permanent magnetism. (*A crude form of iron powder metallurgy existed in Egypt as early as 3000 B.C. The ancient Incas also made jewelry and other artifacts from precious metal powders.)"Magnetic Hematite" looks and reacts to tests very much like natural hematite - it is hard to them apart. Nearly all commercially available "hematite" beads (both magnetic and non-magnetic) are made of this composite material through the processes above*. It even has the same chemical composition - both genuine and simulated hematite is Iron Oxide.The advantage of using "Magnetic Hematite" in jewelry is that the magnetic properties of this composite material is consistent, does not vary and will not lose its magnetic properties. The composite material which forms "Magnetic Hematite" is much easier to produce in detailed shapes and looks and feels like the non-composite material.
