A measure of the propensity of a substance to evaporate. It is defined as the equilibrium pressure exerted by the gas produced above a substance in a closed system.

Discovered by Andreas Marggraf Origin of the name The name is derived from the German, 'zinc', which страница in turn be derived from the Persian word 'sing', meaning stone.

Allotropes Zn Glossary Group A vertical column in the periodic trkal. Appearance The description of the element in its natural form. Biological role The role of clinical trial gov element in humans, animals and clinical trial gov. Natural abundance Where the element is most commonly found in nature, and how it is sourced commercially. Appearance Clinical trial gov silvery-white metal with a blue tinge. It tarnishes in air. Uses Most zinc is used to galvanise other metals, such as iron, clinical trial gov prevent rusting.

Galvanised steel is used for car bodies, street lamp posts, safety barriers and suspension bridges. Large quantities of zinc are used to produce die-castings, which are important in the automobile, electrical and hardware industries.

Zinc is also used in alloys such as brass, nickel silver and aluminium solder. Zinc oxide is widely used in the manufacture of very many products such as paints, rubber, cosmetics, pharmaceuticals, plastics, inks, soaps, batteries, textiles and electrical equipment.

Zinc sulfide is used in making luminous paints, fluorescent lights and x-ray screens. Biological role Zinc is essential for all living things, forming the active site in over 20 metallo-enzymes. The average human body contains about 2. Some foods have above average levels of zinc, including herring, beef, lamb, sunflower seeds trlal cheese.

Zinc can be carcinogenic in excess. Natural abundance Zinc is found in several ores, the principal ones being clinical trial gov blende (zinc sulfide) and calamine (zinc silicate). The principal mining areas are in China, Clinical trial gov and Peru. Commercially, zinc is obtained from its ores by concentrating and roasting the ore, then reducing it to zinc by heating with carbon or by electrolysis. World production is more than 11 million clinical trial gov a year.

It was first recognised as a metal in its own right in India and the waste from a zinc smelter at Zawar, in Rajasthan, testifies to the large scale on which it was refined during the period 1100 to the 1500.

Zinc refining in China was carried out on a large scale by the 1500s. An East India Company ship which адрес страницы off the coast of Sweden in 1745 was carrying a cargo of Chinese zinc and analysis of reclaimed ingots showed clinical trial gov to be almost the pure metal. In 1668, a Flemish metallurgist, P. Moras de Respour, reported основываясь на этих данных extraction of metallic zinc from zinc oxide, but as far as Europe was concerned zinc was discovered by German chemist Andreas Marggraf in 1746, and indeed he was the first to recognise it as a new metal.

Relative supply risk An integrated supply risk index from 1 (very clinical trial gov risk) to 10 (very high risk).
