Sulphide

Barium sulfide is the chemical compound with the formula BaS. This material was once known as "Bologna Stone", the first synthetic phosphor. Currently the chalcogenides of the alkaline earth metals are intensely studied as candidates for short wavelength emitters for electronic displays.[2] BaS is considered to be the most important synthetic material of barium, being the precursor to BaCO3 and the pigment lithopone, ZnS/BaSO4

Cadmium sulfide is a chemical compound with the formula CdS. Cadmium sulfide is yellow in colour and is a semiconductor.[2] It exists in nature as two different minerals, hexagonal greenockite[2] and cubic hawleyite.[3] Cadmium sulfide is a direct band gap semiconductor (gap 2.42 eV[4]) and has many applications for example in light detectors. It forms thermally stable pigments and with the addition of e.g. CdTe, HgS colours ranging from deep red to yellow are formed.

Dimethyl sulfide (DMS) or methylthiomethane is an organosulfur compound with the formula (CH3)2S. Dimethyl sulfide is a water-insoluble flammable liquid that boils at 37 °C (99 °F) and has a characteristic disagreeable odor. It is a component of the smell produced from cooking of certain vegetables, notably corn, cabbage, beetroot and seafoods. It is also an indication of bacterial infection in malt production and brewing. It is a breakdown product of dimethyl sulfoniopropionate (DMSP), and is also produced by the bacterial metabolism of methanethiol.

Iron(II) sulfide is a chemical compound with the formula FeS. In practice, iron sulfides are often non-stoichiometric. Powdered iron sulfide is pyrophoric.

Iron(II) sulfide is a chemical compound with the formula FeS. In practice, iron sulfides are often non-stoichiometric. Powdered iron sulfide is pyrophoric.

Lead(II) sulfide (also spelled sulphide) is a inorganic compound with the formula PbS. It finds limited use in electronic devices. The principal ore of lead is the mineral galena is PbS, and for this reason PbS is the most important compound of lead.

It is gray to yellow-green crystalline solid.

Sodium hydrosulfide is the chemical compound with the formula NaHS. This compound is the product of the half -neutralization of hydrogen sulfide with a sodium-derived base. NaHS is a useful reagent for the synthesis of organic and inorganic sulfur compounds. It is a colorless solid that typically smells like H2S due to hydrolysis by atmospheric moisture. In contrast with Na2S, which is insoluble in organic solvents, NaHS, being a 1:1 electrolyte, is more soluble.
