Fluorite and Fluorspar: Mineral uses and properties
Fluorite is very easy to identify if you consider cleavage, hardness, and specific gravity. It is the only common mineral that has four directions of perfect cleavage, often breaking into pieces with the shape of an octahedron. It is also the mineral used for a hardness of four in the Mohs Hardness
Bentonite / Montmorillonite Clay Powder
Calcium bentonites are often characterized by much lower swelling and liquid limit values compared to natural sodium bentonite. Sodium activated bentonites are produced by the substitution of calcium ions by sodium ions. This transformation can be achieved by the addition of a soluble sodium salt to calcium bentonite. Chemical Formula

Calcium phosphate, tribasic Uses, Side Effects & Warnings
Dec 05, 2019· Calcium is a mineral that is found naturally in foods. Calcium is necessary for many normal functions of the body, especially bone formation and maintenance. Calcium can also bind to other minerals (such as phosphate) and aid in their removal from the body. Calcium phosphate is used to prevent and to treat calcium deficiencies.
Sodium | Chemical formula
The chemical formula of sodium is Na. The syol is derived from the Latin name natrium. Sodium reacts violently with water producing hydrogen gas and sodium hydroxide. Sodium and water ==> hydrogen gas and sodium hydroxide. 2Na + 2H 2 O ==> H 2 + 2NaOH. Sodium metal is stored in paraffin oil to prevent it from reacting with moisture from the air.
