In its most characteristic reaction, the solid decomposes explosively, releasing nitrogen gas: 2 AgN 3 (s) → 3 N 2 (g) + 2 Ag(s). The first step in this decomposition is the production of free electrons and azide radicals; thus the reaction rate is increased by the addition of semiconducting oxides. [4]
In organosilicon chemistry, silanes are a diverse class of charge-neutral organic compounds with the general formula SiR 4. The R substituents can be any combination of organic [1] or inorganic groups. [2] Most silanes contain Si-C bonds, and are discussed under organosilicon compounds. Some contain Si-H bonds and are discussed under hydrosilanes.
Silane can be produced by several routes. [8] Typically, it arises from the reaction of hydrogen chloride with magnesium silicide: . Mg 2 Si + 4 HCl → 2 MgCl 2 + SiH 4. It is also prepared from metallurgical-grade silicon in a two-step process.
Silanes are saturated chemical compounds with the empirical formula Si x H y. They are hydrosilanes, a class of compounds that includes compounds with Si−H and other Si−X bonds. All contain tetrahedral silicon and terminal hydrides. They only have Si−H and Si−Si single bonds. The bond lengths are 146.0 pm for a Si−H bond and 233 pm ...
Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si 3 N 4 (Trisilicon tetranitride) is the most thermodynamically stable and commercially important of the silicon nitrides, [6] and the term ″Silicon nitride″ commonly refers to this specific composition.
Silicon compounds are compounds containing the element silicon (Si). As a carbon group element, silicon often forms compounds in the +4 oxidation state, though many unusual compounds have been discovered that differ from expectations based on its valence electrons, including the silicides and some silanes.
In inorganic chemistry, chlorosilanes are a group of reactive, chlorine-containing chemical compounds, related to silane (SiH 4) and used in many chemical processes. Each such chemical has at least one silicon-chlorine (Si−Cl) bond. Trichlorosilane is produced on the largest scale. The parent chlorosilane is silicon tetrachloride (SiCl 4). [1]
Again there is variation in composition: magnesium silicide is represented by Mg 2 Si, [9] calcium silicide can be represented by Ca 2 Si, CaSi, CaSi 2, Ca 5 Si 3 and by Ca 14 Si 19, [10] strontium silicide can be represented by Sr 2 Si, SrSi 2 and Sr 5 Si 3 [11] and barium silicide can be represented by Ba 2 Si, BaSi 2, Ba 5 Si 3 and Ba 3 Si 4 ...
