Calcium (Ca) does not occur in the free state in nature but its compounds are extremely abundant. It may be produced by the electrolysis of fused calcium chloride, but modern production is by the reduction of lime by aluminium in retorts under a low pressure. The metal calcium is being increasingly used in alloys, and in many metallurgical and chemical operations.
