Product Code : ME-Ca-NN-CU
Calcium is a silvery white metal which is obtained by the electrolysis of molten calcium chloride. Calcium metal melts at 842 °C and boils at 1494 °C; these values are higher than those for magnesium and strontium, the neighbouring group 2 metals. It crystallises in the face-centered cubic arrangement like strontium; above 450 °C, it changes to an anisotropic hexagonal close-packed arrangement like magnesium. Its density of 1.55 g/cm3 is the lowest in its group. It is one of the most abundant metal elements on Earth (41000 ppm), but it never occurs as the pure element, the main deposits being limestone (CaCO₃), Dolomite (CaCO₃.MgCO₃) and Gypsum (CaSO₄.2H₂O). Calcium is harder than lead but can be cut with a knife with effort. While calcium is a poorer conductor of electricity than copper or aluminium by volume, it is a better conductor by mass than both due to its very low density.
ATT is a professional supplier of high-purity Calcium Metal, The purity can be 99%(2N), 99.9%(3N), 99.99%(4N), 99.999%(5N), Calcium Metal is available as disc, granules, ingot, pellets, pieces, powder , rod, wire, sputtering target and in numerous other forms and custom shapes. We also produce Zinc as rods, powder and plates. Other shapes are available by request.

Calcium is harder than lead but can be cut with a knife with effort. While calcium is a poorer conductor of electricity than copper or aluminium by volume, it is a better conductor by mass than both due to its very low density. While calcium is infeasible as a conductor for most terrestrial applications as it reacts quickly with atmospheric oxygen, its use as such in space has been considered. Calcium compounds have many applications; for example, calcium chloride is used extensively to dry gases as it is capable of absorbing moisture from the atmosphere. Calcium oxide (lime), produced by heating limestone, has many applications including the chemical, agricultural, construction and water industries. Calcium is an essential constituent of the human body which contains, on average, 1kg. of the element.
Calcium Metal is available as disc, granules, ingot, pellets, pieces, powder, rod, wire, and sputtering target. Ultra high purity and high purity forms also include metal powder, submicron powder and nanoscale, quantum dots, targets for thin film deposition, pellets for evaporation and single crystal or polycrystalline forms. Elements can also be introduced into alloys or other systems as fluorides, oxides or chlorides or as solutions.

Applications of Calcium Metal
Because calcium reacts exothermically with water and acids, calcium metal coming into contact with bodily moisture results in severe corrosive irritation. When swallowed, calcium metal has the same effect on the mouth, oesophagus, and stomach, and can be fatal. However, long-term exposure is not known to have distinct adverse effects
The largest use of metallic calcium is in steelmaking, due to its strong chemical affinity for oxygen and sulfur. Its oxides and sulfides, once formed, give liquid lime aluminate and sulfide inclusions in steel which float out; on treatment, these inclusions disperse throughout the steel and become small and spherical, improving castability, cleanliness and general mechanical properties. Calcium is also used in maintenance-free automotive batteries, in which the use of 0.1% calcium–lead alloys instead of the usual antimony–lead alloys leads to lower water loss and lower self-discharging.
Due to the risk of expansion and cracking, aluminium is sometimes also incorporated into these alloys. These lead–calcium alloys are also used in casting, replacing lead–antimony alloys. Calcium is also used to strengthen aluminium alloys used for bearings, for the control of graphitic carbon in cast iron, and to remove bismuth impurities from lead.[39] Calcium metal is found in some drain cleaners, where it functions to generate heat and calcium hydroxide that saponifies the fats and liquefies the proteins (for example, those in hair) that block drains.
Besides metallurgy, the reactivity of calcium is exploited to remove nitrogen from high-purity argon gas and as a getter for oxygen and nitrogen. It is also used as a reducing agent in the production of chromium, zirconium, thorium, and uranium. It can also be used to store hydrogen gas, as it reacts with hydrogen to form solid calcium hydride, from which the hydrogen can easily be re-extracted.
