Raite is a rare and beautiful mineral. It was named in 1973 to honor the international scientific expedition of the ship "Ra II" which was built of papyrus. The ship was captained by Thor Heyerdahl, a Norwegian explorer and scientist who was determined to prove the sea worthiness of reed boats. The Ra II was successfully sailed from Safi, Morocco to Barbados in 1970.

Raite is a bit of an oddball mineral in that its structure is hard to classify. It is classified as a phyllosilicate in the Dana classification scheme and as a inosilicate in the Strunz classification scheme. The structure of raite is composed of linked chains of silicates, four chains across. Dana considers this a sheet structure and therefore a phyllosilicate, while Strunz considers this to still be a chain structure and therefore an inosilicate.

Raite is another rare and beautiful agpaitic mineral. Agpaitic minerals are those found in unusual igneous intrusive rocks that contain alkali metals and high concentrations of unusual metals such as titanium and zirconium. These rocks are called agpaites and there are only a few localities around the world that are identified as agpaites. At two of these, raite is found; Mount Saint Hilaire, Quebec, Canada and Mt. Lovozero Massif, Kola Peninsula, Russia. At both sites, raite forms beautiful acicular crystals arranged in sprays, fans, spherulites, rosettes and as crusts. The color is golden-brown to red or even violet with a silky luster. It is associated with other rare minerals and although hard to find, it is certainly a cool mineral to have in a collection.
