Zirconium sheet, strip, foil
Zirconium is hard and simultaneously ductile metal. Ductility it approaches the gold, so it can roll out into very thin foil, of a thickness of a few microns Zirconium sheet and strip have a number of extraordinary qualities, allowing to use them on the front lines of modern industry: instrumentation, experimental chemistry, mechanical engineering, electrical engineering and nuclear energy.
Sheet and strip from the zirconium produced hot and cold rolling. In accordance with GOST, on the surface of finished products acceptable minor defects: risks, colour changes, dents, not beyond the size of the allowed deviation. Color variations are also normalized by the standard and depend entirely on conditions and the shelf life of the material. Dimensions of zirconium sheets vary widely from 5 mm in thickness, 500−800 mm in width and approximately 500−2000 mm in length. At larger sizes the permissible deviation of the length up to 20 mm. Sheets can be dimensional and random length which is a multiple or non-multiple of 100. Properties of zirconium rolled depend on the accompanying impurities. Antimony, sulfur, bismuth, zinc, and lead impair the durability of metal. Sulfur forms on the surface of the sulfide film, which in comparison with the Zirconia has a lower melting point and makes the sheet brittle when bulbs. The main way of purification from impurities is the electrorefining. The sheet is immersed in an electrolyte, and an cathode in this case is another zirconium sheet, the surface of which is deposited the metal in its purest form. A similar process pays for itself, because when the electrorefining is the «anode mud». It is easily decomposed into a number of valuable chemical elements.

Tape is used primarily in instrumentation and electrical engineering for the production of cathodes and anodes, as well as various elements and electric heaters, with a steadily high level of resistance. Most often, these elements are made of zirconium tape with a thickness of 5−20 microns. Zirconium sheet is widely used in the chemical industry, nuclear energy and engineering. Cold-rolled sheets with additive of up to 2.5% of niobium rolled are annealed in vacuum, the surface is etched. This sheet holds the radiation has a narrow capture cross section for thermal neutrons and resistance to aggressive environments. Apply for cases of chemical reactors, and also covers heat-only boilers nuclear reactors.
