Zinc - chemical element which is under atomic number 30 in D. I. Mendeleyev's table. Metal is an element II of group of a secondary subgroup.
Simple substance is rather plastic transitional metal which possesses in silver-white color. Under normal conditions metal fragile, and on air grows dull (becoming covered by a thin layer of oxide of ZnO zinc).
In pure form zinc is applied to restoration of precious metals (gold, silver).
Including zinc is applied to protection of steel and cast iron against corrosion (galvanizing).
Thanks to the fact that zinc is the most electropositive metal and is steady in water solutions it is used in production of various accumulators.
Also zinc is used at paint production (zinc whitewash).
At production of semiconductors from use telluride, selenit, phosphide isulfid zinc.
Zinc dust is applied in pyrotechnics for it is received the painted flame in blue color. Including it is used in production of rare and precious metals.
Selenit of zinc is still used for production of optical glasses with very low coefficient of absorption on average infrared range.
