Zirconium

Thanks to their economy and reliability against wear, titanium(Ti) and zirconium(Zr) are widely used as the coatings of drills, milling machines and other tools. Moreover, zirconium is applied in decorative coatings. We supply both materials as sputtering targets with the finished products and semi-finished products.

 
We can supply planar, rotary titanium-zirconium targets and customized titanium-zirconium targets.

It is a chemical element, its chemical symbol is Zr, its atomic number is 40, is a high melting point metal, light gray. The density is 6.49g/cm 3. The melting point is 1852 ± 2.001 ℃ and the boiling point is 4377 ℃.

The valence is + 2, + 3 and + 4. The first ionization energy is 6.84 ev. The surface of zirconium is easy to form a layer of oxide film with luster, so the appearance of zirconium is similar to that of steel. It has corrosion resistance, soluble in hydrofluoric acid and aqua regia. At high temperature, it can react with non-metallic elements and many metal elements to form solid solution compounds.

Zirconium and zirconium alloys have a series of characteristics, such as low density, high specific strength, corrosion resistance, irradiation resistance, excellent wear resistance, excellent processability, non-toxic, non-magnetic, small cross-section of thermal neutron absorption.

It is popular used in those files:

(1) Glass coating &Watch coating

(2) Ocean and space equipments

(3) Medical use equipment

(4) Sewage disposal

In view of the fact that zirconium and zirconium alloys have low density, high specific strength, corrosion resistance, radiation resistance, excellent wear resistance, excellent processing performance, non-toxic, non-magnetic, compared with traditional stainless steel, copper, nickel, titanium and other metal alloys, zirconium and zirconium alloys have excellent corrosion resistance, which can resist the corrosion of most organic acids, inorganic acids, strong bases and some molten salts. In wastewater treatment, food processing, strong acid production industry, it is mainly used in equipment and components with high requirements for corrosion resistance, such as reactor, acid resistant pump, heat pump, heat exchange pipe, immersion tank, acid resistant impeller, valve, agitator, nozzle and container lining. The zirconium equipment and devices used by American chemical enterprises have been in use for more than 25 years without obvious corrosion damage. The conversion rate is as high as 85% ~ 90%, which greatly improves the production efficiency of enterprises. In the process of deep-sea exploration, zirconium alloy can not only withstand the erosion of sea water and sand, seawater corrosion and fluid friction and wear, but also adapt to the alternating temperature environment of - 200 ~ 200 ℃. This is due to the low thermal expansion coefficient of zirconium, which can be stably and continuously used. The absorption cross section is small.
