Because its water absorption is fast, and for neutral compounds, all kinds of organic compounds can not be chemical reaction, so it is commonly used desiccant. It is often used to dry organics that cannot be dried with anhydrous calcium chloride.

Used as feed, it is the component of bones and teeth of livestock, and it is needed for the normal development of bones, and it is also the activator of various enzymes, which plays an important role in the metabolism of sugar and protein. It can also be used as fertilizer or compound fertilizer, and also as raw material for producing magnesium oxide.
