Wholesale for fluorite slices

Fluorite, also known as calcium fluoride, is a common halide mineral. It is a compound whose component is calcium fluoride. It is an important mineral for extracting fluorine. Fluorite has many colors and can also be transparent and colorless. Transparent and colorless fluorite can be used to make special optical lenses. Fluorite also has many uses, such as flux for steelmaking and aluminum production, used to make opalescent glass, enamel products, catalysts in high-octane fuel production, etc. Fluorite is generally granular or blocky, with a glassy luster, mostly green or purple. Fluorite often emits blue-green fluorescence under ultraviolet or cathode ray irradiation, and its name is derived from this feature. Chemical composition: CaF2

Crystal structure: The unit cell is a face-centered cubic structure, and each unit cell contains 4 calcium ions and 8 fluoride ions.
Crystal state: crystalline body
Crystal system: isometric crystal system
Crystal habit: often cubes, octahedrons, rhombic dodecahedrons and aggregates, and can also be strip-shaped dense block aggregates.
Common colors: green, blue, brown, yellow, pink, purple, colorless, etc.
Luster: vitreous to sub-vitreous.
Cleavage: four groups of complete cleavage.
Mohs hardness: 4.
Density: 3.18 (+0.07, -0.18) g/cm3.
Optical characteristics: homogeneous.
Pleochroism: none.
Refractive index: 1.434 (±0.001).
Birefringence: none.
UV fluorescence: varies with different varieties, generally with very strong fluorescence, may have phosphorescence.
Absorption spectrum: no characteristics, large changes, generally strong absorption.
Magnification inspection: color bands, two-phase or three-phase inclusions, it can be seen that the cleavage is triangular in development.

Special optical effect: color change effect.
Optimization treatment:
Heat treatment: black and dark blue are often heat-treated to blue, stable, avoid heating above 300°C, and difficult to detect.
Filling treatment: fill surface cracks with plastic or resin to ensure that they will not crack during processing.
Irradiation treatment: Colorless fluorite turns purple when irradiated, but it fades quickly when exposed to light and is very unstable.
