Pliny the Elder described a soft stone from Persia used in cups that may have been fluorite. //-->\n , Sir Humphry Davy originally suggested the name fluorine, taking the root from the name of "fluoric acid" and the -ine suffix, similarly to other halogens. HF has a long history of destructive behaviour, claiming the lives of several chemists in the 1800s, including the Belgian Paulin Louyet, and the Frenchman Jérôme Nicklès. 1543-1544. However, Karl O. Christe argued in favor of it in 1986. Due to its richness and its colors, the fluorite has always been fascinating for the man. Wikipedia. High pressure was thus created inside the solid. 1894, 7ème série, t. II, 5. These brave scientists were battling to be the first to isolate elemental fluorine (F 2) from its various compounds, using electrolysis. Moissan's fluorine cell, from his 1887 publication . Fluorine: A Paradoxical Element, Volume Five, deals with the link between fluorine, humanity and the environment. Other researchers paid a high price to the even more toxic effects of this element, without for so much succeeding in isolating the element: G. and T. Knox were severely intoxicated and the Belgium chemist P. Louyet lost his life. 3). 3. The work was carried out by DuPont scientist Dr. Tomas Midgley Jr. DuPont and GM formed a joint venture in 1930 to market the new product; in 1949 DuPont took over the business. In 1986 the International Henri Moissan Prize was created for stimulating research in the field of fluorine chemistry. In 1670 a recipe containing Bohemian emerald (now known as calcium fluoride, CaF 2) was used to etch glass. var addy55767 = 'tressaud' + '@'; From 1890 on, he worked on an even more challenging task than that of isolating fluorine - that of artificially creating diamonds. //--> var path = 'hr' + 'ef' + '='; It exists bound to other atoms, and scientists need to do chemical experiments to get fluorine by itself. Fluorine is a relatively new element in human applications. Today the world production of synthetic diamonds is estimated at around 450-500 million carats. The industrial use of fluorite, fluorine's source mineral, was first described by early scientist Georgius Agricola in the 16th century, in the context of smelting. "We remains to be discovered is whether the electricity will not decompose the hydrofluoric acid into its liquid form, when we have removed the water to the greatest extent, by bringing the hydrogen to one side and the oxy-fluoric to the other.’ In his reply in February 1811, Davy does not concede that a single body be present as Ampère asserts, but rather, considers that this body also contains oxygen.  Moissan's report to the French Academy of making fluorine showed appreciation for the feat: "One can indeed make various hypotheses on the nature of the liberated gas; the simplest would be that we are in the presence of fluorine.". Ben-Gurian University of the Negev. In the late 1600's minerals which we now know contain fluorine were used in etching glass. 1967, 22, 340 ; W. Massa, Z. Anorg. Fluorine and its highly toxic gaseous compounds, together with the carbon monoxide that was emitted from his electric furnace had doubtless weakened his health and may well have been responsible for his low resistance to the infection. ...in recognition of the great services rendered by him in his investigation and isolation of the element fluorine...The whole world has admired the great experimental skill with which you have studied that savage beast among the elements. Fluorine is a pale yellow, gaseous element at room temperature. The periodic table is a chart that shows how elements are related to one another. Phys.
