A black magnetic iron oxide found in nature as magnetite, also obtained synthetically (as from iron by heating in steam or from a ferrous salt and an alkali by precipitation and oxidation), and used chiefly as a pigment and a polishing compound but also as a catalyst, in magnetic inks, in metallurgy, in ferrites for the electronic industry and in coatings for magnetic tapes.

Composés du fer. [...] L'oxyde magnétique Fe3O4, ou oxyde salin, constitue la pierre d'aimant naturelle; on l'obtient artificiellement par combustion du fer ou par action de la vapeur d'eau. C'est une poudre noire qu'on peut considérer comme une combinaison des deux autres oxydes [ferreux et ferrique].

OBS

oxyde de fer : ce terme désigne chacun des composés du fer avec l'oxygène, comme l'oxyde ferreux (FeO), l'oxyde ferrique (Fe2O3), et l'oxyde ferrosoferrique (Fe3O4).

CONT

SECAR 41 is a hydraulic binder with an alumina content of approximately 47% and an iron oxide content of approximately 5%. [It] is composed mainly of calcium aluminate phases, which makes it an ideal binder for refractory applications. SECAR 41 is particularly rich in monocalcium aluminate ... which imparts excellent properties to mortars and concretes.

CONT

The most important cement compounds formed on fusion are monocalcium aluminate (CA) and tricalcium pentaluminate (C3A5); furthermore, some pentacalcium pentaluminate and small amounts of dicalcium aluminosilicate, dicalcium silicate, and tetracalcium aluminoferrite are also present. Both monocalcium aluminate and tricalcium pentaluminate hydrate initially to a gel CaAl2(OH)8·6H2O, which gradually changes to a very stable, crystalline complex Ca3Al2(OH)10·3H2O and a gel of aluminium hydroxide Al(OH)3.

PHR

Hydrated monocalcium aluminate.

[Osmium tetroxide is a] volatile compound used e.g. for post-fixation (1-2% w/v in phosphate or cacodylate buffer); the specimen is immersed in (or exposed to the vapour of) the solution. OsO4 may cross-link and stabilize e.g. lipids by reacting with their double bonds. Longer exposure to OsO4 may be used for positive staining in electron microscopy.
