sulfide mineral - Definition, Examples, Identification ,Sulfides - Materion

Sulfide mineral, any member of a group of compounds of sulfur with one or more metals Most of the sulfides are simple structurally, exhibit high symmetry in their crystal forms, and have many of the properties of metals, including metallic luster and electrical conductivitySulfides Overview Inorganic sulfides are compounds of various metals with sulfur Sulfides are generally not thought of as high temperature materials, but at least 30 metallic sulfides display refractory properties which indicate potential uses at elevated temperatur.

Iron(II) sulfide - WikipediaProtection of metal from the hydrogen sulfide corrosion

Some of the hydrogen sulfide will react with metal ions in the water or solid to produce iron or metal sulfides, which are not water-soluble These metal sulfides, such as iron(II) sulfide, are often black or brown, leading to the color of sludge Pyrrhotite is a waste product of the Desulfovibrio bacteria, a sulfate reducing bacteriaSince the discovery and development of oil and gas fields containing hydrogen sulfide in the production wells, the problem of protection of metal from the hydrogen sulfide corrosion arose acutely Hydrogen sulfide H2S is aggressive gas, provoking acid corrosion, which in this case is called the hydrogen sulfide corrosion.

Metal Sulfides - an overview - ScienceDirect TopicsSolubility Products - New Mexico State University

Metal sulfide catalysts absorb strongly in the visible region of the spectrum due to their narrow band gap and can therefore have a strong solar conversion efficiency The earliest example of metal sulfide photocatalyst for N 2 reduction to NH 3 was a binary CdS/Pt wafer reported in [13]The solubility product constant of lead(II) sulfide is much smaller than that of zinc sulfide, so it is the least soluble sulfide When a solution that is 010 M in each metal ion and 030 M in hydronium ion is saturated with hydrogen sulfide, lead(II) sulfide precipitates, but zinc ion remains in solution.

Finally, trace metal concentrations increased with decreasing pH (Figure 7) while sulfate concentrations remained relatively constant (Figure 6) This indicates that the increase in trace metal concentrations was the result of increased aqueous mobility at the low pH values, rather than increased metal sulfide ,Jan 13, &#; Because recent thermodynamic calculations by researchers at Washington University in St Louis provide plausible evidence that "heavy metal snow," which blankets the surface of upper altitude Venusian rocks, is composed of both lead and bismuth sulfid.
