Zirconium: the essentials Zirconium: historical information. Zirconium was discovered by Martin Heinrich Klaproth in 1789 at Berlin, Germany. Origin of name: from the Arabic word zargun meaning gold colour. The name zircon probably originated from the arabic zargun, which describes the colour of the gemstone now known as zircon (ZrSiO4).

Zircon Zircon (/ˈzɜrkɒn/ or /ˈzɜrkən/ ; including hyacinth or yellow zircon) is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate and its corresponding chemical formula is Zr SiO4.ircon is ubiquitous in the crust of Earth. It occurs as a common accessory mineral in igneous rocks (as primary crystallization products), in metamorphic rocks and as detrital grains in sedimentary rocks. Large zircon crystals are rare.

- The periodic table had two vacant slots below manganese and finding these missing elements, technetium and rhenium, proved difficult. Rhenium was the lower one and indeed it was the last stable, non-radioactive, naturally-occurring element to be discovered. In 1905, Masataka Ogawa found it in the mineral thorianite from Sri Lanka.

Zirconium Element Facts Zirconium is very poor at absorbing neutrons. It is therefore useful in nuclear energy applications such as in the cladding (outer layer) of fuel rods through which it is important that neutrons can travel easily. Zirconium is used as to make surgical instruments and is used in steel alloys as a hardening agent. As a result of its exceptional corrosion resistance, zirconium is used extensively in the chemical industry in corrosive environments where zirconium’s alloys can be found in pipes, fittings and heat exchangers.

Zirconium The principal commercial source of zirconium is the silicate mineral, zircon (ZrSiO 4), which is found primarily in Australia, Brazil, India, Russia, South Africa and the United States, as well as in smaller deposits around the world.he name of zirconium is taken from the name of the mineral zircon, the most important source of zirconium. The word zircon comes from the Persian word zargun زرگون, meaning gold-colored.

- History and Uses: Radium was discovered by Marie Sklodowska Curie, a Polish chemist, and Pierre Curie, a French chemist, in 1898. Marie Curie obtained radium from pitchblende, a material that contains uranium, after noticing that unrefined pitchblende was more radioactive than the uranium that was separated from it.oday, radium can be obtained as a byproduct of refining uranium and is usually sold as radium chloride (RaCl 2) or radium bromide (RaBr 2) and not as a pure material. Radium's most stable isotope, radium-226, has a half-life of about 1600 years.

Zirconium Naturally occurring zirconium is composed of five isotopes. 90 Zr, 91 Zr, 92 Zr and 94 Zr are stable. 94 Zr can undergo double beta decay (not observed experimentally) with a half-life of more than 1.10×10 17 years.96 Zr has a half-life of 2.4×10 19 years, making it the longest-lived radioisotope of zirconium.wenty-eight artificial isotopes of zirconium have been synthesized, ranging in atomic mass from 78 to 110. 93Zr is the longest-lived artificial isotope, with a half-life of 1.53×10 6 years. 110 Zr, the heaviest isotope of zirconium, is also the shortest-lived, with an estimated half-life of only 30 milliseconds.

- Zircon, ZrSiO4, the principal ore, is pure ZrO2 in crystalline form having a hafnium content of about 1%. Zirconium also occurs in some 30 other recognized mineral species. Zirconium is produced commercially by reduction of chloride with magnesium (the Kroll Process), and by other methods.

Who Discovered Zirconium Who Discovered Zirconium. 25 Jul, 2012 who designed 0. Zirconium is a gray-white metal with a similar appearance to titanium. It is a chemical element represented by the symbol Zr and atomic number 40. It is never found as a free metal because it reacts with water, but it is present in more than 140 minerals.

- In the Middle Ages colourless gemstones of zircon were thought to be an inferior kind of diamond, but that was shown to be wrong when a German chemist, Martin Klaproth (1743-1817), analysed one in 1789 and discovered zirconium.

40 Zr Zirconium Description: Named for the gemstone in which it was first discovered (which itself is named from the Arabic word meaning gold color), zirconium is a hard, lustrous, gray-white metal. It is common in very cool stars and has been found in the Sun and in meteorites. Zirconium seems to be common in Moon rocks. It is resists water, most acids and bases, so much so that it is used as a shield against corrosive compounds in the chemical industry. It will react with air under certain circumstances.

Hafnium: historical information Hafnium was discovered by Dirk Coster and George Charles von Hevesy at 1923 in Denmark. Origin of name: from the Latin name Hafnia meaning Copenhagen. Hafnium was thought to be present in various zirconium minerals many years prior to its discovery, in 1923, which was credited to Dirk Coster and George Charles von Hevesey. It was finally identified in zircon (a zirconium ore) from Norway, by means of X-ray spectroscopic analysis.

- Then suddenly, late in 1938, Otto Hahn (pictured at right with Lisa Meitner) and Fritz Strassmann (pictured at left) discovered a fundamentally new and unexpected exception. After irradiating uranium with neutrons, they were surprised to detect barium, an element only about half of the mass of uranium.The conclusion was inescapable; they had split the uranium atom into two parts. They had discovered nuclear fission -- the splitting of the atom.Two physical properties of nuclear fission are particularly exciting and important; splitting the uranium nucleus with a neutron releases energy and a few additional neutrons.hen suddenly, late in 1938, Otto Hahn (pictured at right with Lisa Meitner) and Fritz Strassmann (pictured at left) discovered a fundamentally new and unexpected exception.

Zirconium (IV) silicate Zirconium silicate, also zirconium orthosilicate, (Zr Si O4) is a chemical compound, a silicate of zirconium.It occurs in nature as the zircon, a silicate mineral. Zirconium silicate is also sometimes known as zircon flour. Zirconium silicate is usually colorless, but impurities induce various colorations.It is insoluble in water, acids, alkali and aqua regia.t is separated from sand by electrostatic and electromagnetic methods. Also, the compound can be made by fusion of SiO2 and ZrO2 in an arc furnace, or by reacting a zirconium salt with sodium silicate in an aqueous solution.

- Caesium was eventually discovered by Gustav Kirchhoff and Robert Bunsen in 1860 at Heidelberg, Germany. They examined mineral water from Durkheim and observed lines in the spectrum which they did not recognise, and that meant a new element was present.

- Zirconium is a chemical element with symbol Zr and atomic number 40. The name of zirconium is taken from the name of the mineral zircon, the most important source of zirconium. The word zircon comes from the Persian word zargun زرگون, meaning gold-colored. It is a lustrous, grey-white, strong transition metal that resembles hafnium and, to a lesser extent, titanium.

What Is Pitchblende? (Uraninite) Pitchblende contains many other radioactive elements that can be traced back to the decay of uranium, such as radium, lead, helium and several actinide elements. Pitchblende was the source of discovery for several elements. In 1789, Martin Heinrich Klaproth discovered and identified uranium as a new element from pitchblende. In 1898, Marie and Pierre Curie discovered the element radium while working with pitchblende. In 1895, William Ramsay was the first to isolate helium from pitchblende.

Zircon Zircon (/ˈzɜrkɒn/ or /ˈzɜrkən/ ; including hyacinth or yellow zircon) is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate and its corresponding chemical formula is Zr SiO4.ircon is rare within mafic rocks and very rare within ultramafic rocks aside from a group of ultrapotassic intrusive rocks such as kimberlites, carbonatites, and lamprophyre, where zircon can occasionally be found as a trace mineral owing to the unusual magma genesis of these rocks.
