6.11E: Structure - Zinc Blende (ZnS) - Chemistry LibreTexts

Introduction. Zinc sulfide (ZnS) is a unique compound that forms two types of crystalline structures. 1 These two polymorphs are wurtzite and zincblende (also known as sphalerite). 3 Wurtzite has a hexagonal structure, while zincblende is cubic. 1 It is characterized by single bonds between each atom and maintenance of a 1:1 zinc to sulfur ratio. 4

Sphalerite. Sphalerite is a mineral that is the chief ore of zinc. It consists largely of zinc sulfide in crystalline form. But almost always contains variable iron.

zinc sulfides - an overview | ScienceDirect Topics

David Rickard, in Developments in Sedimentology, 2012. 7.1. Zinc. Zinc sulfide occurs as two polymorphs, cubic sphalerite and hexagonal wurtzite. Sphalerite is the stable phase at low temperatures and is a fairly common trace mineral in sulfidic sediments.

Sphalerite - Wikipedia

Sphalerite (which is also known as Blende), is an important ore of zinc and can make a rather attractive cabinet specimen as well. It can have excellent luster and associates with many beautifully colored minerals making it one of the best enhancers of many fine mineral specimens.

Sphalerite: Mineral information, data and localities.

Sphalerite, also known as blende or zinc blende, is the major ore of zinc. When pure (with little or no iron) it forms clear crystals with colours ranging from pale yellow (known as Cleiophane ) to orange and red shades (known as Ruby Blende ), but as iron content increases it forms dark, opaque metallic crystals (known as Marmatite ).

Zinc Sulfide - Assignment Point

Solid zinc sulfide is found in two different crystal forms, alpha (wurtzite) and beta (sphalerite), which have hexagonal and cubic structures, respectively. The beta crystalline (sphalerite) is the more stable form of ZnS. The chemical formula of zinc sulfide is ZnS, and its molar mass is 97.47 g/mol. The chemical structure of ZnS is simple and consists of the zinc metal attached to a sulfur ...

Structure World: Zincblende (ZnS) - ilpi.com

ZnS occurs in two common polytypes, zincblende (also called sphalerite) and wurtzite. The two types have these features in common: a 1:1 stoichiometry of Zn:S a coordination of 4 for each ion (4:4 coordination) tetrahedral coordination Zincblende/sphalerite is based on a fcc lattice of anions whereas wurtzite is derived from an hcp array of anions. In both structures, the cations occupy one of ...

The two principal minerals containing lead and zinc are galena and sphalerite. These two minerals are frequently found together along with other sulfide minerals, but one or the other may be predominant. Galena may contain small amounts of impurities including the precious metal silver, usually in the form of a sulfide. When silver is present in sufficient quantities, galena is regarded as a ...
