Spiritus fumans – stannic chloride, formed by distilling tin with corrosive sublimate. Spirit of hartshorn – ammonia, formed by the decomposition of sal-ammoniac by unslaked lime. Spirit of salt/ acidum salis – the liquid form of hydrochloric acid (also called muriatic acid), formed by mixing common salt with oil of vitriol.

The solid Al(OH) 3 Gibbsite is then calcined (heated to over 1100 °C) to give aluminium oxide: [7] 2 Al(OH) 3 → Al 2 O 3 + 3 H 2 O. The product aluminium oxide tends to be multi-phase, i.e., consisting of several phases of aluminium oxide rather than solely corundum. [17] The production process can therefore be optimized to produce a ...
Congruent melting occurs during melting of a compound when the composition of the liquid that forms is the same as the composition of the solid. It can be contrasted with incongruent melting. This generally happens in two-component systems. To take a general case, let A and B be the two components and AB a stable solid compound formed by their ...
Organoaluminium chemistry is the study of compounds containing bonds between carbon and aluminium. It is one of the major themes within organometallic chemistry. [1] [2] Illustrative organoaluminium compounds are the dimer trimethylaluminium, the monomer triisobutylaluminium, and the titanium-aluminium compound called Tebbe's reagent.
Reddish-purple thulium(II) compounds can be made by the reduction of thulium(III) compounds. Examples of thulium(II) compounds include the halides (except the fluoride). Some hydrated thulium compounds, such as TmCl 3 ·7H 2 O and Tm 2 (C 2 O 4) 3 ·6H 2 O are green or greenish-white. [17] Thulium dichloride reacts very vigorously with water.
Organolithium compounds are electrically non-conducting volatile solids or liquids that melt at low temperatures, and tend to form oligomers with the structure (RLi) x where R is the organic group. As the electropositive nature of lithium puts most of the charge density of the bond on the carbon atom, effectively creating a carbanion ...
Boron can form intermetallic compounds and alloys with such metals of the composition M n B, if n > 2. [110] Ferroboron (15% boron) is used to introduce boron into steel ; nickel-boron alloys are ingredients in welding alloys and case hardening compositions for the engineering industry.
