Ferrite magnets are superb in damp, wet or marine environments – Ferrite magnets are corrosion free. Because the iron is already in a stable oxidized form in its structure, the iron cannot oxidize ("rust") any further when in water. Strontium Ferrite (SrO.6Fe2O3) magnets and Barium Ferrite (BaO.6Fe2O3)
2.2 Methods of ferrite preparation Two steps are necessary for preparation of hexagonal ferrite. In the first step, homogeneous mixture is prepared from the raw starting materials strontium - or barium - and iron-inorganic compounds by pre-sintering. In the second step, the calcinate is treated by heating to achieve ordered ferrite structure.
Strontium-90, a radioactive isotope, is a by-product of nuclear reactors and present in nuclear fallout. It has a half-life of 28 years. It is absorbed by bone tissue instead of calcium and can destroy bone marrow and cause cancer.

A ferrite is a ceramic material made by mixing and firing large proportions of iron(III) oxide (Fe 2 O 3, rust) blended with small proportions of one or more additional metallic elements, such as barium, manganese, nickel, and zinc. They are both electrically non-conductive, meaning that they are insulators, and ferrimagnetic, meaning they can easily be magnetized or attracted to a magnet.
