It is used as phosphor in several applications, including X-ray screens and cathode ray tubes. EC Number 215-251-3. Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Wurtzite has a hexagonal closest packing structure (hcp), which is characterized by 12 ions in the corners of each unit that create a hexagonal prism (seen in Fig. Licensed under the Creative Commons Attribution-Share Alike 3.0 Unported, 2.5 Generic, 2.0 Generic and 1.0 Generic license. with zinc sulfide. The sulfate concentration is reduced in a single step from 5–15 to 0.05 g l −1, while the zinc concentration is reduced from 100 to <0.3 mg l −1, recovering about 8.5 tons of zinc sulfide a day [71, 43]. The beta crystalline (sphalerite) is the more stable form of ZnS. Description Zinc sulfide is an inorganic compound with the chemical formula ZnS. 77205. An important condition of getting highly efficient phosphors is that these sulfides must first be prepared to the highest possible chemical purity before the necessary amount of activator can be… Cadmium sulfide mixed with zinc sulfide (8:92) C.I. Structure-wise, the zinc blende structure is more thermodynamically favored, however, because of the wurtzite structures slow construction, both forms of ZnS can be found. Formula and structure: The chemical formula of zinc sulfide is ZnS, and its molar mass is 97.47 g/mol. ESPI Metals. Zinc and sulfur react with each other violently to produce zinc sulfide; the reaction is accompanied by a vigorous evolution of gas, heat, and light: eCl@ss 38150412 . (accessed January 11, 2021). AZoM. Solutions of sulfide salts are corrosive. NACRES NA.22 1 Product Result 81.379 g mol-1. A break down of cubic closest packing. lead sulfide and dimethyl sulfide. EINECS 269-773-1. Zinc Sulfide is available as 99.99 pure (metals basis) 1-2 micron powder, CVD grade granules or tablets, or as a nano-powder. In luminescence: Sulfide-type phosphors, activators, fluxes. 2. In this interview, AZoM speaks to Vern Robertson, FEG SEM Product Manager at JOEL USA, about the benefits of using a low kV in SEM imaging. Sigma-Aldrich offers a number of Zinc sulfide products. Zinc sulfide (ZnS) is a unique compound that forms two types of crystalline structures.

Zinc sulphide, Zinc monosulfide, Sachtolith HDS, Pigment White 7, sulfanylidenezinc, sulfanylidenezinc, doped zinc sulfide, Sphalerite Chemical Identifiers Linear Formula *Please select more than one item to compare Wurtzite has a hexagonal structure, while zincblende is cubic. Therefore, four sulfur atoms surround each zinc atom and four zinc atoms surround each sulfur atom.2 The coordination number, the number of of electron pairs donated to a metal by its ligands, for both zinc an sulfur is four.1,2 The difference between wurtzite and zincblende lies in the different arrangements of layers of ions.2. For better coatings and plastics . It mainly occurs in the minerals sphalerite and wurtzite. Oz. 12442-27-2. (2018, August 23). Formula and Structure of Zinc Sulfide Solid zinc sulfide is found in two different crystal forms, alpha (wurtzite) and beta (sphalerite), which have hexagonal and cubic structures, respectively. Zinc sulfate and its hydrates are colourless solids. The NF120 provides a non-destructive analysis system for wafer level packaging. Zinc sulfide is transparent and white in color. Do you have a review, update or anything you would like to add to this article? Zinc + Sulfur . Although this mineral is usually black because of various impurities, the pure material is … MDL number MFCD00011301. (Author: Maghémite Date: May 5, 2008. ESPI Metals.
