Zinc Sulfide (ZnS)-Cubes/Squares introduce:


Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. 

Chemical formula:ZnS

Molar mass:97.474 g/mol

Density:4.090 g/cm3

Melting point:1,850 °C (3,360 °F; 2,120 K) (sublime)

Solubility in water:negligible

Band gap:3.54 eV (cubic, 300 K)

                   3.91 eV (hexagonal, 300 K)

Refractive index (nD):2.3677


Although this mineral is usually black because of various impurities, the pure material is white, and it is widely used as a pigment. In its dense synthetic form, zinc sulfide can be transparent, and it is used as a window for visible optics and infrared optics.
