15 Deville, Henri Etienne Sainte-Claire
SUBJECT AREA: Metallurgy[br]b. 11 March 1818 St Thomas, Virgin Islandsd. 1 July 1881 Boulogne-sur-Seine, France[br]French chemist and metallurgist, pioneer in the large-scale production of aluminium and other light metals.[br]Deville was the son of a prosperous shipowner with diplomatic duties in the Virgin Islands. With his elder brother Charles, who later became a distinguished physicist, he was sent to Paris to be educated. He took his degree in medicine in 1843, but before that he had shown an interest in chemistry, due particularly to the lectures of Thenard. Two years later, with Thenard's influence, he was appointed Professor of Chemistry at Besançon. In 1851 he was able to return to Paris as Professor at the Ecole Normale Supérieure. He remained there for the rest of his working life, greatly improving the standard of teaching, and his laboratory became one of the great research centres of Europe. His first chemical work had been in organic chemistry, but he then turned to inorganic chemistry, specifically to improve methods of producing the new and little-known metal aluminium. Essentially, the process consisted of forming sodium aluminium trichloride and reducing it with sodium to metallic aluminium. He obtained sodium in sufficient quantity by reducing sodium carbonate with carbon. In 1855 he exhibited specimens of the metal at the Paris Exhibition, and the same year Napoleon III asked to see them, with a view to using it for breastplates for the Army and for spoons and forks for State banquets. With the resulting government support, he set up a pilot plant at Jarvel to develop the process, and then set up a small company, the Société d'Aluminium at Nan terre. This raised the output of this attractive and useful metal, so it could be used more widely than for the jewellery to which it had hitherto been restricted. Large-scale applications, however, had to await the electrolytic process that began to supersede Deville's in the 1890s. Deville extended his sodium reduction method to produce silicon, boron and the light metals magnesium and titanium. His investigations into the metallurgy of platinum revolutionized the industry and led in 1872 to his being asked to make the platinum-iridium (90–10) alloy for the standard kilogram and metre. Deville later carried out important work in high-temperature chemistry. He grieved much at the death of his brother Charles in 1876, and his retirement was forced by declining health in 1880; he did not survive for long.[br]BibliographyDeville published influential books on aluminium and platinum; these and all his publications are listed in the bibliography in the standard biography by J.Gray, 1889, Henri Sainte-Claire Deville: sa vie et ses travaux, Paris.Further ReadingM.Daumas, 1949, "Henri Sainte-Claire Deville et les débuts de l'industrie de l'aluminium", Rev.Hist.Sci 2:352–7.J.C.Chaston, 1981, "Henri Sainte-Claire Deville: his outstanding contributions to the chemistry of the platinum metals", Platinum Metals Review 25:121–8.LRDBiographical history of technology > Deville, Henri Etienne Sainte-Claire

19 Moissan, Ferdinand-Frédéric-Henri
SUBJECT AREA: Chemical technology[br]b. 28 September 1852 Paris, Franced. 20 February 1907 Paris, France[br]French chemist, the first to isolate fluorine, and a pioneer in high-temperature technology.[br]His family, of modest means, moved in 1864 to Meaux, where he attended the municipal college; he returned to Paris before completing his education and apprenticed himself to a pharmacist. In 1872 he began work as a laboratory assistant at the Musée d'Histoire Naturelle, while continuing studies in chemistry. He qualified as a pharmacist at the Ecole Supérieure de Pharmacie in 1879, and by this time he had decided that his main interest was inorganic chemistry. His early investigations concerned the oxides of iron and related metals; his work attracted the favourable attention of Sainte-Claire Deville and was the subject of his doctoral thesis. In 1882 Moissan married Leonie Lugan, whose father provided generous financial support, enabling him to pursue his researches with greater freedom and security. He became, successively, Professor of Toxicology at the Ecole in 1886 and of Inorganic Chemistry in 1899. In 1884 Moissan began both his investigation of the compounds of fluorine and his attempts to isolate the highly reactive element itself. Previous attempts by chemists had ended in failure and sometimes injury. Moissan's health, too, was affected, but in June 1886 he succeeded in isolating fluorine by electrolysing potassium fluoride in hydrogen fluoride at −50°C (−58°F) in platinum apparatus. He was then able to prepare further compounds of fluorine, some of technological importance, such as carbon tetrafluoride. At the same time, Moissan turned his attention to the making of artificial diamonds. To achieve this, he devised his celebrated electric-arc furnace; this was first demonstrated in December 1892 and consisted of two lime blocks placed one above the other, with a cavity for a crucible and two grooves for carbon electrodes, and could attain a temperature of 3,500°C (6,332°F). It seemed at first that he had succeeded in making diamonds, but this attempt is now regarded as a failure. Nevertheless, with the aid of his furnace he was able to produce and study many substances of technological importance, including refractory oxides, borides and carbides, and such metals as manganese, chromium, uranium, tungsten, vanadium, molybdenum, titanium and zirconium; many of these materials had useful applications in the chemical and metallurgical industries (e.g. calcium carbide became the main source of acetylene).[br]Principal Honours and DistinctionsNobel Prize in Chemistry 1906.BibliographyThere are several listings of his more than 300 publications, such as Lebeau, cited below. Major works are Le Four électrique (1897, Paris) and Le Fluor et ses composés (1900, Paris).Further ReadingCentenaire de l'Ecole supérieure de pharmacie de l'Université de Paris 1803–1903,1904, Paris, pp. 249–57.B.Harrow, 1927, Eminent Chemists of Our Time, 2nd edn, New York, pp. 135–54, 374– 88.P.Lebeau, 1908, "Notice sur la vie et les travaux de Henri Moissan", Bulletin Soc. chim. de France (4 ser.) 3:i–xxxviii.LRDBiographical history of technology > Moissan, Ferdinand-Frédéric-Henri

20 Le Chatelier, Henri Louis
SUBJECT AREA: Metallurgy[br]b. 8 November 1850 Paris, Franced. 17 September 1926 Miribel-les-Echelle, France[br]French inventor of the rhodium—platinum thermocouple and the first practical optical pyrometer, and pioneer of physical metallurgy.[br]The son of a distinguished engineer, Le Chatelier entered the Ecole Polytechnique in 1869: after graduating in the Faculty of Mines, he was appointed Professor at the Ecole Supérieure des Mines in 1877. After assisting Deville with the purification of bauxite in unsuccessful attempts to obtain aluminium in useful quantities, Le Chatelier's work covered a wide range of topics and he gave much attention to the driving forces of chemical reactions. Between 1879 and 1882 he studied the mechanisms of explosions in mines, and his doctorate in 1882 was concerned with the chemistry and properties of hydraulic cements. The dehydration of such materials was studied by thermal analysis and dilatometry. Accurate temperature measurement was crucial and his work on the stability of thermocouples, begun in 1886, soon established the superiority of rhodium-platinum alloys for high-temperature measurement. The most stable combination, pure platinum coupled with a 10 per cent rhodium platinum positive limb, became known as Le Chatelier couple and was in general use throughout the industrial world until c. 1922. For applications where thermocouples could not be used, Le Chatelier also developed the first practical optical pyrometer. From hydraulic cements he moved on to refractory and other ceramic materials which were also studied by thermal analysis and dilatometry. By 1888 he was systematically applying such techniques to metals and alloys. Le Chatelier, together with Osmond, Worth, Genet and Charpy, was a leading member of that group of French investigators who established the new science of physical metallurgy between 1888 and 1900. Le Chatelier was determining the recalescence points in steels in 1888 and was among the first to study intermetallic compounds in a systematic manner. To facilitate such work he introduced the inverted microscope, upon which metallographers still depend for the routine examination of polished and etched metallurgical specimens under incident light. The principle of mobile equilibrium, developed independently by Le Chatelier in 1885 and F.Braun in 1886, stated that if one parameter in an equilibrium situation changed, the equilibrium point of the system would move in a direction which tended to reduce the effect of this change. This provided a useful qualitative working tool for the experimentalists, and was soon used with great effect by Haber in his work on the synthesis of ammonia.[br]Principal Honours and DistinctionsGrand Officier de la Légion d'honneur.
