Alumen

L. alumen, alum) The ancient Greeks and Romans used alum as an astringent and as a mordant in dyeing. In 1761 de Morveau proposed the name alumine for the base in alum, and Lavoisier, in 1787, thought this to be the oxide of a still undiscovered metal. [Pg.31]

The word alum is derived from the Latin alumen, which was appHed to several astringent substances, most of which contained aluminum sulfate (20). Unfortunately, the term alum is now used for several different materials. Papermakers alum or simply alum refers to commercial aluminum sulfate. Common alum or ordinary alum usually refers to potash alum which can be written in the form K SO Al2(SO 24H20, or it can refer to ammonium alum, ammonium aluminum sulfate. The term is also appHed to a whole series of crystallised double sulfates [M(l)M (lII)(SO 2 12H20] having the same crystal stmcture as the common alums, in which sodium and other univalent metals may replace the potassium or ammonium, and other metals may replace the alurninum. Even the sulfate radical may be replaced, by selenate, for example. Some examples of alums are cesium alum [7784-17-OJ,... [Pg.176]

Aluminium (Al, [Ne]3,v23/ ), name after the Latin word alumen (alum, K2A16(0H)12(S04)4, used in ancient times as an astringent). Discovered (1825) in Denmark by Hans Christian Oersted. [Pg.480]

Aluminium - the atomic number is 13 and the chemical symbol is Al. Although the name was originally called alumium, it was later changed to aluminum. Internationally, the element is referred to as alviminium, to conform with the ium ending of most metallic elements. The name derives from the Latin, alum and alumen for stringent , since the early Romans called any substance with a stringent taste alum. The element was known in prehistoric times. In 1825, the Danish physicist, Hans Christian Oersted, isolated impure aluminium. The pure metal was first isolated by the German chemist Friedrich Wohler in 1827. [Pg.4]

ORIGIN OF NAME From the Latin word alumen, or aluminis, meaning "alum," which is a bitter tasting form of aluminum sulfate or aluminum potassium sulfate. [Pg.178]

The term alumen plumosum has had a long association with asbestos. Alumen (= alum) is a general term for naturally occurring hydrous alkali aluminum sulfates. These are efflorescent mineral materials of fibrous, feathery appearance. Confusion with the more durable silicate composition asbestos was not settled until 1741, by Tourneforte following a visit to asbestos deposits in Asia Minor. [Pg.43]

Alumen plumosum A Latin name given to the fibrous and feathery types of natural alum (hydrous alkali aluminum sulfates) and other efflorescent natural sulfates. Because of visible similarity, these materials were confused with asbestos by some early writers, and the term remained in use as a synonym of asbestos for many years. [Pg.191]

Aluminum Al 13 Hans Christian Oersted Denmark Latin word "alumen" meaning "alum"... [Pg.96]

Aluminum was discovered in 1825 by Hans Christian Oersted. Its name comes from the Latin word alumen for alum. Gallium was discovered by P. Boisbaudran in 1875, and its name is derived from the Latin name for France, Gallia. The existence of eka-aiuminum ... [Pg.207]

Alumen. The round, scissile, and liquid species are of use in medicine. There is another kind, which is called Alumen Affar or in Arabic Usnen and in Latin, Sparrow s Dung, several varieties of which are enumerated by Serapion and Avicenna.
