Zirconium ball valve

Zirconium ball valve in is mainly used for high corrosion resistance requirements of equipment, such as used in the manufacture of the kettle, acid resistant heat pump, heat exchanger, immersion, exhaust valve of the impeller, zirconium, mixer, spray nozzle, thermowells, catheters and container liner and environmental protection equipment, etc. Many production of fertilizer, resin, plastic, acid of chemical equipment and important parts are using zirconium.

Zirconium, applied to the atomic energy industry and used as a corrosion under high temperature and high pressure chemical materials, etc.

One of the high melting point metal, the pale grey. Density of 6.49 g/cm 3. The melting point to 1852 + 2 ℃, boiling point of 4377 ℃. Valence + 2, + 3 and + 4. The first ionization energy of 6.84 electron volts. Zirconium surface is easy to form a layer of oxide film, gloss, so the appearance is similar to steel. Corrosion resistance, not soluble in hydrofluoric acid and aqua regia; High temperature, can react with nonmetallic elements and many metal elements, generate solid solution of compound.

Zirconium metal outer surface of the steel, surface is covered by dense oxide layer under normal temperature, but there are still a metallic luster. Zirconium powder for dark grey. Zirconium metal melting point is 1852 ℃, density 6.49 g/cm 3. Its plasticity is good, is easy to be processed into plate, wire, etc. When heated to a large number of zirconium in absorption of oxygen, hydrogen, nitrogen and other gases can be used as a hydrogen storage material. The corrosion resistance of zirconium is better than titanium, close to niobium, tantalum. Zirconium and hafnium is chemically similar to history, and the symbiotic together of the two metals, and other radioactive substances. The zirconium content in the earth's crust in the 20th, almost equal with chromium. At present, the nature of industrial value containing zirconium minerals, basically have zircon and baddeleyite. Zirconium is rare metal, but abundant in the earth's crust is more than copper, tin, zinc, etc.
