Fluorite, is a main component of CaF2. It is glassy and colorful. It is commonly used as a flux to reduce melting temperature, improve chemical reactivity, and help to absorb and remove sulfur, phosphorus, carbon and other impurities in slag.It is widely used in steelmaking, ferroalloy production and non-ferrous metal smelting.It has lower refractive index, lower radiation hardness, better luminescence properties, and availability from natural sources such as fluorite.Fluoride crystals have a wide range of applications in optical and laser fields.
