About Zinc

Zinc is a softish metal of light grey color and is one of so called transition metals. Its name comes from a similar German word which is believed to be a copy of an old Persian word meaning stone. It is impossible to find pure zinc on our planet, but it can be extracted from a number of minerals and compounds. Zinc is essential for normal chemical processes in living organisms, and in micro-doses it exists in our enzymes. Large or even medium dozes of zinc can be toxic. This metal is widely used as a galvanizer, in such products as lamp posts, some parts of automobiles, etc. As a part of an alloy with copper called brass, zinc is used for producing parts of musical instruments, and zinc is also used to produce many other alloys. Oxides of this chemical element are used for producing rubber, plastic, textiles, soaps, cosmetics, electrical components, and many other goods.
