Tin(IV) sulfide is a compound with the formula SnS2. A brown, water-insoluble solid, it is a semiconductor with band gap 2.2 eV. [ 5 ] It occurs naturally as the rare mineral berndtite .
A disulfide ensemble is a grouping of all disulfide species with the same number of disulfide bonds, and is usually denoted as the 1S ensemble, the 2S ensemble, etc. for disulfide species having one, two, etc. disulfide bonds. Thus, the (26–84) disulfide species belongs to the 1S ensemble, whereas the (26–84, 58–110) species belongs to ...
Tin(II) sulfide is an inorganic compound with the chemical formula is SnS. A black or brown solid, it occurs as the rare mineral herzenbergite (α-SnS).It is insoluble in water but dissolves with degradation in concentrated hydrochloric acid. Tin(II) sulfide is insoluble in ammonium sulfide.
Tin sulfide can refer to either of these chemical compounds: Tin(II) sulfide, SnS; Tin(IV) sulfide, SnS 2 This page was last edited on 2 December ...
Tin is a post-transition metal in group 14 of the periodic table of elements. It is obtained chiefly from the mineral cassiterite, which contains stannic oxide, SnO 2. Tin shows a chemical similarity to both of its neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and the slightly more stable
Titanium(III) sulfide is air- and water-stable at normal temperatures and unlike titanium disulfide does not give off an odor of hydrogen sulfide. In hot sulfuric acid, Ti 2 S 3 first forms a blue-gray slurry and then a colorless solution, while in cold concentrated sulfuric or nitric acid it forms a green-colored solution.
The standard Gibbs free energy of formation (G f °) of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of a substance in its standard state from its constituent elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298.15 K or 25 °C).
Titanium nitride (TiN) is a refractory solid exhibiting extreme hardness, thermal/electrical conductivity, and a high melting point. [13] TiN has a hardness equivalent to sapphire and carborundum (9.0 on the Mohs scale), [14] and is often used to coat cutting tools, such as drill bits. [15]
