The symbol of Zirconium is Zr. Zirconium’s name comes from the Persian word, zargun, which means “gold-like.” The main gemstone of zirconium is zircon. In 1789, Klaproth carefully examined the materials made out of zircon and came across a new earth metal, ZrO2. We now call this Zirconia. Martin Klaproth is a german chemist who discovered uranium and cerium as well as zirconium. Another impure sample of the metal was found in 1824 by the swedish chemist, Berzelius. He isolated the impure metal by heating a mixture of potassium and potassium zirconium fluoride in a small decoposition process. Zirconium in a pure form was not available until 1914. https://www.britannica.com/biography/Martin-Heinrich-Klaproth

Zirconium is produced from the mineral zircon. Lunar rocks have been shown to have high zircon content compared to terrestrial rocks. Based on the closely observed lunar rock samples from the many different Apollo missions, lots of them are found in S-type stars and are in the sun and meteorites. Zirconium can also be in at least 30 other recognized mineral species. The mineral deposits from zirconium can be found all over the world. Zirconium comes from zirconium dioxide (baddeleyite) and zircon. These minerals are found in placer deposits and wind swept sands. They are mined in Australia, South Africa, USA, Russia, and Brazil.

Since Zircon has a high occurance of the changing of light, it made the cubic crystalline form of Zirconium oxide be produced as a synthetic gemstone called cubic Zirconium. This is Zirconium’s most well-known use and cubic Zirconium is the most economically important competitor for diamonds. Zirconia, the impure oxide, is used for laboratory cups that stand against heat shock, the technique used for furnace linings, and for refractory materials in glass and ceramics. Zirconium is used in surgical appliances, photoflash bulbs, to collect the materials in vacuum tubes, steel with two or more metals, lamp threads, poison ivy lotions as a form of carbonate, and more. Zirconium has almost perfect conductivity with niobium at low temperatures. Then, it is used to make supercondicuctive magnets which can lead to lots of electric power. Zircalay, made out of two or more metals is an alloy. It was produced for nuclear power. Nuclear power generated for business is more than 90% of Zirconium metal production. The power reactors can use up to half a million linear feat of Zirconium containing tubing.

Zirconium can be many different colors, but the most common is clear or a grayish color. It is hard, shiny, and ductile. Similar to the other metals in Group IVB, powedered Zirconium can set on fire automatically in the air, and it does not react with mineral acids or alkalis. Also, Zirconium has a big resistance to corrosion. Zirconium is a popular gemstone for many different pieces of jewlery.
