  Biography of Moissan   (Site not responding. Last check: 2007-10-22)
Born on September 28, 1852, Henri Moissan was a French chemist and Professor of chemistry
Moissan was apprenticed to an apothecary at the age of eighteen, but in 1872, decided to study under Edmond Fremy at the Musée d'Histoire Naturelle.
Moissan's use of the electric furnace allowed him to prepare many uncommon metals, among them uranium, tungsten, vanadium, chromium, manganese, titanium, and molybdenum.

He died suddenly in Paris in February 1907, shortly after his return from receiving the Nobel Prize in Stockholm.

 Moissan, Henri
After attending the Museum of Natural History and the School of Pharmacy in Paris, Moissan became professor of toxicology (1886) and of inorganic chemistry (1889) at the School of Pharmacy and professor of inorganic chemistry (1900) at the Sorbonne.
In 1892 Moissan developed the electric arc furnace and used it to prepare numerous new compounds and to vaporize substances previously regarded as infusible.
Moissan's scientific works include Le Four électrique (1897; "The Electric Furnace"), Le Fluor et ses composés (1900; "Fluorine and Its Compounds"), and Traité de chimie minérale, 5 vol.

Moissan nació en París el 28 de setiembre de 1852 y cursó estudios secundarios en el Colegio de Meaux, donde encontró un profesor, James, que supo darle una excelente preparación básica en matemática, física y química.
Moissan trabajó al principio en un laboratorio privado, pero tuvo que acudir pronto a la hospitalidad que le ofrecieron Debray y Troost, en el Laboratorio de la Sorbona y aceptar algunos cargos docentes que le dejaban muy poco tiempo para investigar.
Los esfuerzos de Moissan tienen éxito cuando, por rigurosa lógica, llega a la electrólisis del ácido fluorhídrico anhidro a –30ºC, con fluorhidrato de potasio, en un aparato de platino cerrado con tapones de espato fluor.

 Moissan, Henri
Moissan songea alors à mesurer la solubilité du carbone dans le fer et dans ses alliages, opération pour laquelle il lui aurait fallu disposer d'un four atteignant de hautes températures, et qui n'existait pas à l'époque.
Moissan prépara du bore amorphe et pur, ce qui lui permit d'étudier puis de fabriquer les borures d'hydrogène, tandis que l'un de ses élèves, Binet, obtenait de son côté toute une série de borures métalliques.
Au début du XXe siècle, Moissan proposa le vanadium pour servir d'élément d'alliage dans les aciers et les fontes; ces alliages au molybdène ou au vanadium jouèrent un grand rôle durant la Première Guerre mondiale, et leur utilisation s'est développée aujourd'hui et a acquis une importance considérable, toujours dans la fabrication du matériel d'armement.

 Fluorine
Since platinum was one of the few substances that might resist fluorine, Moissan constructed equipment from this metal platinum and lowered the temperature (-50°C) to reduce fluorine's activity.
Moissan made a full study of the properties of fluorine and its reactions with other elements.
Since Moissan had recently isolated fluorine (the most active of the known elements), Ramsey sent him a sample of argon to determine whether it would react with fluorine.

 Youngfolk's Book of Invention
In the year 1892 Henri Moissan, a French chemist, attached, like the Curies, to the University of Paris, had made a rather rough electric furnace of the "resistance" type, so termed because the heat is produced by the high electrical resistance of the material with which the furnace is charged.
The body of Moissan’s furnace, also the lid, were constructed of blocks of lime, lime being one of the most perfect of nonconductors of heat.
Moissan’s method of making them was to dissolve coke dust in molten iron, using a crucible made of carbon.

Back in his lab Moissan was using the arc for a very different purpose: to power his electric arc furnace, in which the carbon rods burned so hot they nearly made him artificial diamonds (see the November 1998 column).
Moissan was le noodleur extraordinaire who got the Nobel in 1906, isolated fluorine (without killing himself) and wrote more than 300 scientific papers.
In the winter of 1897 he also provided a young Polish physicist, living in Paris, with some uranium powder, and she began to investigate its mysterious ability to "electrify" the air around it.

First isolated in 1886 by the French chemist Henri Moissan, fluorine was originally referred to as the "gas of Lucifer" and the great "tiger" of chemistry.
Fluorine was not successfully isolated until 1886 when Ferdinand-Frédéric-Henri Moissan, a student of Fremy’s successfully electrolyzed dry potassium acid fluoride in anhydrous liquid hydrogen fluoride in a platinum U-tube using platinum-iridium electrodes using methyl chloride to cool the apparatus to -50 Celsius.
Although an advocate of extreme cleanliness in his laboratory, Moissan was subjected to fluorine poisoning many times and died prematurely as a result.
