It is for this reason that zircon is taken for a soft qualitative diamond in a very long period of time. The two chemists have made remarkable contributions to the discovery and purification of zirconium. In , German chemist Martin proved that the zircon is not diamond, which clarified the misunderstanding of zircon. Through heating the zircon with reactive compound sodium hydroxide, he found that the two substances generated an oxide.
Martin believed that the oxide containing a new element. This delayed progress in studying the element. The element zirconium is named after the mineral in which it was discovered, zircon.

They describe an alloy containing niobium, titanium, zirconium and molybdenum NbTiZrMo and its benefits for dental and other medical devices. The zirconium in the alloy gives higher mechanical properties as well as reduces the melting temperature along with titanium , further stabilization, and improved corrosion resistance.
Another patent filed by Shuichi Miyazaki, Heeyoung Kim and Yosuke Sato, Japanese scientists, in describes a zirconium alloy that has super elastic properties that can be used in biological and medical fields.
Zirconium is alloyed with titanium, niobium and either tin or aluminum, or both. The alloy is similar to the elasticity of human bones, according to values given by Young's modulus, making it an ideal material for uses inside the human body including artificial bones, joints, and teeth as well as orthodontic wires, stents, bone plates, and other medical implants. Even though zirconium and other elements in alloys for dental and medical uses are nontoxic, there are still ongoing studies to ensure that the materials themselves don't have adverse side affects over the long term.
One such study by a group of scientists in Italy, published in PLOS One in , on a group of obese participants found that there might be a link between zirconium implants and some health problems, such as inflammation and skeletal and connective tissue disorders.
The amount of change in certain biological markers miRNAs was very small and it is believed that they accumulate over time, which can make it difficult to pin point the exact cause. While additional research is needed, the study helped in the understanding the link between the human body and implanted medical devices.
The goal, according to the authors, is to take advantage of mrRNAs to assist in wound healing and host-implant integration. Live Science.

Jump to main content. Periodic Table. Glossary Allotropes Some elements exist in several different structural forms, called allotropes. Discovery date Discovered by Martin Heinrich Klaproth Origin of the name The name is derived from the Arabic, 'zargun', meaning gold coloured. Allotropes -.

Appearance The description of the element in its natural form. Biological role The role of the element in humans, animals and plants. Natural abundance Where the element is most commonly found in nature, and how it is sourced commercially. Uses and properties. Image explanation. The Ancient Egyptians used zircon gemstones in jewellery.
For the Ancient Egyptians the scarab beetle represented here was a symbol of regeneration and creation, conveying ideas of transformation, renewal and resurrection. A hard, silvery metal that is very resistant to corrosion.
Zirconium does not absorb neutrons, making it an ideal material for use in nuclear power stations. Nuclear reactors can have more than , metres of zirconium alloy tubing. With niobium, zirconium is superconductive at low temperatures and is used to make superconducting magnets.
Zirconium metal is protected by a thin oxide layer making it exceptionally resistant to corrosion by acids, alkalis and seawater. For this reason it is extensively used by the chemical industry.
Zirconium IV oxide is used in ultra-strong ceramics. It is used to make crucibles that will withstand heat-shock, furnace linings, foundry bricks, abrasives and by the glass and ceramics industries. It is so strong that even scissors and knives can be made from it. It is also used in cosmetics, antiperspirants, food packaging and to make microwave filters.
Zircon is a natural semi-precious gemstone found in a variety of colours. The most desirable have a golden hue. The element was first discovered in this form, resulting in its name. Cubic zirconia zirconium oxide is a synthetic gemstone. The colourless stones, when cut, resemble diamonds.
Biological role. Zirconium has no known biological role. It has low toxicity. Natural abundance. Zirconium occurs in about 30 mineral species, the major ones being zircon and baddeleyite. More than 1. Most baddeleyite is mined in Brazil. Zirconium metal is produced commercially by first converting zircon to zirconium chloride, and then reducing the chloride with magnesium. Help text not available for this section currently. Elements and Periodic Table History.
Gems that contain zirconium were known in ancient times as zircon. Klaproth failed to isolate the pure metal itself, and Humphry Davy also failed when he tried electrolysis in Totally pure zirconium was only produced in by the Dutch chemists Anton Eduard van Arkel and Jan Hendrik de Boer by the decomposition of zirconium tetraiodide ZrI 4. These days the metal is produced in bulk by heating zirconium tetrachloride ZrCl 4 with magnesium. Atomic data.
