Calcium - Element information, properties and uses

Calcium is what is known as an essential element, meaning that it is an element which is absolutely necessary for life processes. Which is what the old milk TV adverts were trying to tell us after all. Calcium is used to produce the minerals contained in bones, shells and teeth through a process called biomineralisation.

The Properties and Uses of Zinc Metal

Strength: Zinc is a weak metal with a tensile strength less than half that of mild carbon steel. It is generally not used in load-bearing appliions, although inexpensive mechanical parts can be die cast from zinc. Toughness: Pure zinc has low toughness and is generally brittle, but zinc alloys generally have high impact strength compared to other die casting alloys.

Difference Between Calcium and Calcium Carbonate
