When was zirconium invented




















Equally important is their low toxicity. Zirconium metal has an oxidised surface which is both hard and impervious to chemical attack making it ideal not only for chemical plants but for body implants such as hip replacement joints. Zirconium-aluminium alloy is used for top of the range bicycle frames because it combines strength and lightness. Zirconium metal had some hidden assets which suddenly brought it to prominence in the late s; it was found to be the ideal metal for inside nuclear reactors and nuclear submarines.

It does not corrode at high temperatures, nor absorb neutrons to form radioactive isotopes. Even today the nuclear industry buys almost all of the metal that is produced and some nuclear reactors have more than kilometres of zirconium tubing. Zirconium is used to make the cladding for uranium oxide fuel elements.

Finally, we have two zirconium materials with extreme properties, one which it displays when very cold, the other when it is heated to high temperatures. The first is a zirconium-niobium alloy which becomes superconducting below 35 Kelvin - o C in other words it will conduct electricity with no loss of energy.

The second is zirconium tungstate ZrW 2 O 8 which actually shrinks as you heat it up, at least until it reaches o C when it decomposes into the two metal oxides. John Emsley unlocking the secrets of element number 40, zirconium. And you can find out some more about John's favourite elements in a series he has written for the RSC's Education in Chemistry which is online at rsc.

Next time on Chemistry in its Element, life's a gas with Mark Peplow. Little did those humble cyanobacteria realize what they were doing when two and a half billion years ago, they started to build up their own reserves of energy-rich chemicals, by combining water and carbon dioxide.

Powered by sunlight, they spent the next two billion years terraforming our entire planet with the waste product of their photosynthesis, a rather toxic gas called oxygen. So join us next week for a breath of fresh air and the story of oxygen. I'm Chris Smith, thanks for listening, see you next time.

For this reason, the stones were thought for a long time to be a soft type of diamond. In the Middle Ages, many people believed zircon aided sleep, promoted riches and wisdom, and warded off evil spirits. He made the discovery while studying a sample of zircon from Ceylon, today called Sri Lanka. Although many chemists of the time thought it was a form of alumina , Klaproth suspected that the mineral contained a new element.

He was able to extract zirconium dioxide from zircon, but he was unable to remove oxygen from the substance. Still, he recognized that he had discovered a new element. Klaproth first named the new element Zirkonerde zircon earth, or zirconia. Approximately , patients over the past four decades with zirconia prosthetics have shown no negative responses. Zirconia is also widely used in dental restorations, according to Zirconia Concept , and is typically stabilized with yttria ZrO 2 Y 2 O 3.

The yttria-zirconia compound has many benefits over other materials. It is more compatible with the human body and has twice the flexural strength and four times the compression resistance of steel. It also has greater resistance to acids bases found in many foods. Other new ideas for using zirconium alloys in the medical field include a patent filed in by James Davidson and Lee Tuneberg, American inventors.

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.
