Calcium - АО "Чепецкий механический завод"
Calcium is also widely used in ferrous and non-ferrous metallurgy. The Plant produces calcium metal in the form of ingots, lumps, turnings, crus and granules. The Plant has developed procedures of manufacturing products of calcium alloys with magnesium, aluminium and nickel.
Calcium metal reacts with water, evolving hydrogen gas at a rate rapid enough to be noticeable (unlike its sister magnesium) but not fast enough at room temperature to generate much heat. Part of the slowness of the calcium-water reaction results from the.
