1798799Paris: Chez Fuchs et Guillaume 1798. 1st Edition. FIRST EDITION OF TWO PAPERS BY VAUQUELIN REPORTING THE DISCOVERY OF BERYLIUM. <br /> <br /> Louis Nicolas Vauquelin 16 May 1763 - 14 November 1829 was a French pharmacist and chemist who reports in this paper his discovery of a new ‘earth' obtained by pulverizing gemstone emerald before melting with three times its mass of potassium hydroxide" Walsh Beryllium Chemistry 7. In beryl beryllium aluminum silicate he found an earth oxide that superficially resembled alumina aluminum oxide but was insoluble in alkali and did not form alum. At the suggestion of the editors of Annales de Chimie Vauquelin named it glucina from the sweetness of its sulfate but when first isolated in 1828 by Friedrich Wohler and independently Antoine Bussy it was renamed beryllium DSB Vol. 13 p. 597. <br /> <br /> Though both Beryl and emerald were known as early as 77 A. D. they were not thought to be identical in any way. In 1797 the French mineralogist René Just Haüy noticed that the crystallographic structure of the two minerals seemed similar. Haüy urged Vauquelin to fully determine the chemical composition of each. <br /> <br /> As to the import and uses of Beryllium the national laboratory at Los Alamos states: "Beryllium is used as an alloying agent in producing beryllium copper which is extensively used for springs electrical contacts spot-welding electrodes and non-sparking tools. It is applied as a structural material for high-speed aircraft missiles spacecraft and communication satellites. Other uses include windshield frame brake discs support beams and other structural components of the space shuttle. Beryllium is used in nuclear reactors as a reflector or moderator for it has a low thermal neutron absorption cross section. It is used in gyroscopes computer parts and instruments where lightness stiffness and dimensional stability are required. The oxide has a very high melting point and is also used in nuclear work and ceramic applications" Periodic Table of Elements LANL Los Alamos National Laboratory Portal. <br /> <br /> ALSO INCLUDED: Martin Heinrich Klaproth report on the discovery of tellurium. Additionally Klaproth discovered or co-discovered zirconium 1789 titanium 1792 strontium 1793 chromium 1797 mellitic acid 1799 and cerium 1803 DSB Vol. 7 p. 394.

The first paper was simultaneously printed in Mem.de l'Institut. Because of its many coloured compounds Fourcroy and Haüy suggested the name 'chromium' for the new metal. Greek chroma-colour.In 1797 Vauquelin began his own studies of Siberian red lead. He was convinced that the mineral contained a new element. None of the elements then known could account for his results. He reported "a new metal possessing properties entirely unlike those of any other metal." A year later Vauquelin was able to isolate a small sample of the metal itself. He heated charcoal nearly pure carbon with a compound of chromium chromium trioxide Cr 2 O 3 . When the reaction was complete he found tiny metallic needles of chromium metal.
