Wurtzite GudangMovies21 Rebahinxxi LK21
Wurtzite is a zinc and iron sulfide mineral with the chemical formula (Zn,Fe)S, a less frequently encountered structural polymorph form of sphalerite. The iron content is variable up to eight percent. It is trimorphous with matraite and sphalerite.
It occurs in hydrothermal deposits associated with sphalerite, pyrite, chalcopyrite, barite and marcasite. It also occurs in low-temperature clay-ironstone concretions.
It was first described in 1861 for an occurrence in the San José Mine, Oruro City, Cercado Province, Oruro Department, Bolivia, and named for French chemist Charles-Adolphe Wurtz. It has widespread distribution. In Europe it is reported from Příbram, Czech Republic; Hesse, Germany; and Liskeard, Cornwall, England. In the US it is reported from Litchfield County, Connecticut; Butte, Silver Bow County, Montana; at Frisco, Beaver County, Utah; and from the Joplin district, Jasper County, Missouri.
Structure
The wurtzite group includes cadmoselite (CdSe), greenockite (CdS), mátraite (ZnS), and rambergite (MnS), in addition to wurtzite.
Its crystal structure is called the wurtzite crystal structure, to which it lends its name. This structure is a member of the hexagonal crystal system and consists of tetrahedrally coordinated zinc and sulfur atoms that are stacked in an ABABABABAB pattern.
The unit cell parameters of wurtzite are (-2H polytype):
a = b = 3.81 Å = 381 pm
c = 6.23 Å = 623 pm
V = 78.41 Å3
Z = 2

Wurtzite - Wikipedia
Wurtzite is a zinc and iron sulfide mineral with the chemical formula (Zn,Fe)S, a less frequently encountered structural polymorph form of sphalerite. The iron content is variable up to eight percent. [5] It is trimorphous with matraite and sphalerite. [2]
Hexagonal crystal family - Wikipedia
The wurtzite structure is non-centrosymmetric (i.e., lacks inversion symmetry). Due to this, wurtzite crystals can (and generally do) have properties such as piezoelectricity and pyroelectricity , which centrosymmetric crystals lack.
The Mineral wurtzite - The Mineral and Gemstone Kingdom
Wurtzite is a rare, high temperature polymorph of the common mineral Sphalerite. It forms at temperatures above 2192º F (1200º C) as hexagonal crystals. An ornamental stone known as Schalenblende (an intergrowth of Wurtzite, Sphalerite, and often Galena) is usually referenced with Wurtzite but is more often listed as a variety of Sphalerite.
Wurtzite | Zinc Sulfide, Hexagonal Structure, Semiconductor
wurtzite, a zinc sulfide mineral that occurs typically in Potosí, Bolivia; Butte, Mont.; and Goldfield, Nev. It is a rare and unstable (at temperatures below 1,020° C, [1,870° F]) hexagonally symmetrical modification of sphalerite , to which it inverts crystallographically; it may be made artificially from sphalerite by rapid cooling from ...

Wurtzite - an overview | ScienceDirect Topics
Wurtzite is a crystal structure that consists of a hexagonal close-packed arrangement of oxygen anions with metal cations occupying the tetrahedral interstices. It is found in oxides such as ZnO and BeO.

Wurtzite - Ohio Department of Natural Resources
Wurtzite (ZnS) is a zinc sulfide mineral that is normally brownish black, orange brown, reddish brown, or black in color. Wurtzite is commonly used in manufacturing processes and can be found in veins of ironstone concretions from black shales.
