In its pure form, calcium is a silvery-white metal, although it is never found in this free state naturally.It is, however, one of the most abundant substances on Earth, comprising approximately 3.64% of the earth''s crust.

Synthesis of precipitated calcium carbonate: a review

3/9/2017· Precipitated calcium carbonates are usually produced, either in the industries for commercial purpose or in the laboratory for research using two main methods: by the solid–liquid route, which involves a direct reaction between Ca 2+ and CO 3 2− in an aqueous solution (Kim et al. 2005; Kimura and Koga 2011), and the solid–liquid–gas route, where CO 2 is bubbled through a slurry of Ca

Beryllium, Calcium and Magnesium: Properties, Uses

Metallic calcium has relatively few uses. However, calcium compounds are well known and widely used. The starting point for the manufacture of most calcium compounds is limestone. Limestone occurs naturally in large amounts and used in the production of metals. Another important use of lime is in pollution control.
