There are two crystallographic sites, with the metal cations (Cu, Zn, In) and S occupying the 4a (0, 0, 0) and 4c (¼, ¼, ¼) crystallographic sites, respectively. Each S atom is surrounded by four cation atoms in a tetrahedral geometry, as shown in 2InS4, Cu1.15Zn1 Atomistic simulation techniques were used to investigate the surface energies and stabilities of the sphalerite form of ZnS. The results show that for pure ZnS the lowest energy surfaces are type ...Zinc sulfide (ZnS) is a unique compound that forms two types of crystalline structures. These two polymorphs are wurtzite and zincblende (also known as sphalerite). Wurtzite has a hexagonal structure, while zincblende is cubic. It is characterized by single bonds between each atom and maintenance of a 1:1 zinc to sulfur ratio.
Sphalerite, also known as zinc blende and black-jack, is a zinc sulfide mineral that crystallizes in the form of masses, botryoidal, cubes, tetrahedral crystals, and dodecahedral crystals. Its most commonly silver and grey, but can also be seen as red, black, yellow, brown, green, and colorless. Sphalerite is a sulfide mineral with the chemical formula S. It is the most important ore of zinc. Sphalerite is found in a variety of deposit types, but it is primarily in sedimentary exhalative, Mississippi-Valley type, and volcanogenic massive sulfide deposits. It is found in association with galena, chalcopyrite, pyrite , calcite, dolomite, quartz, rhodochrosite, and fluorite.
