Fluorite, also known as fluorite. A common mineral in nature that can coexist with various other minerals and is produced in many parts of the world. It has 5 effective variants. The equiaxed crystal system is mainly composed of calcium fluoride (CaF ₂). Crystallize into octahedra and cubes. The crystal has a glassy luster, bright and varied colors, brittle texture, a Mohs hardness of 4, a melting point of 1360 ℃, and complete cleavage properties. Some samples can emit light under conditions such as friction, heating, and ultraviolet radiation. [1-3]
This mineral comes from volcanic magma. During the cooling process of magma, the gas water solution separated by magma contains fluorine. As the solution rises along the cracks, the fluoride ions in the gas water solution combine with the calcium ions in the surrounding rocks to form calcium fluoride. After cooling and crystallization, fluorite is formed. [4] Exists in rocks such as granite, pegmatite, and syenite.
Due to its brittle and soft texture, it is not often used as a gemstone. In industry, fluorite is the main source of fluorine and can be extracted to prepare fluorine elements and various compounds. Fluorite specimens with bright colors and beautiful crystal shapes can be used for collecting, decorating, and carving handicrafts.
