fluorite

Description

Also called fluorite,Is a kind of mineral,Its main composition is calcium fluoride,impurity is more ,Ca is often be replaced by Y ,Ce and rare earth element .In addition also contain a small amount of Fe2O3, SiO2 and trace of Cl, O3, He, etc.The nature of fluorite often show bright colors,Low hardness than a knife,Fluorite for cubic system.Single crystal main is the cube, the minority is a rhombic dodecahedron, octahedron..on Cube crystal often appear gridded stripe which parallel with the arris ,Aggregate for granular and crystal cluster, banded, block, etc.
