Ferroso-ferric oxide

The eventual result is the production of a thick, porous film of coarse magnetite (ferroso-ferric oxide or ferrous-ferrite), as shown below. This corrosion product is of no operational benefit and further hinders efficient heat transfer. 

Incendiary Soap consisted of a mixture of Ba nitrate 30.4, paraffin 19.4, Mg 11.3, A1 11.1, rosin 10.9, ferroso-ferric oxide 9.1, NC 4.4 gritty siliceous material 2.6%, compressed into a regular soap bar. Its method of ignition by the Japanese is not known...

When ferroso-ferric ammonium carbonate (see p. 202) is decomposed by a hot concentrated solution of potassium hydroxide in the absence of air, hydrated ferroso-ferric oxide separates out, which, when dried at 100° C., corresponds in composition to the formula Fe203.4Fe0.5H20. It is readily acted on with air, yielding hydrated ferric oxide, Fe203.H20.10... 

When exposed to steam at red heat ferrous sulphide is decomposed, yielding hydrogen, hydrogen sulphide, and ferroso-ferric oxide.3 Thus —... 

Complex Iron Carbonates.—Complex ammonium iron carbonates have been prepared in solution by adding excess of ammonium carbonate to ferrous or ferric salts in aqueous solutions. Ferric ammonium carbonate solution is blood-red in colour, and stable when kept in a closed vessel, but deposits ferric hydroxide on evaporation. Ferrous ammonium carbonate yields a colourless solution, which, upon oxidation in a limited supply of air, yields doubly refracting green prisms of basic ferroso-ferric ammonium carbonate, NH4.C03.Fe.C03.Fe.C03.Fe0.2H20. This, when treated with alkali hydroxides, yields magnetic ferroso-ferric oxide (see p. 144).1... 

The oxidation of acetaldehyde may also be carried out at temperatures of 80° to 100° C. by means of oxidation towers either in the presence or absence of a catalyst.127 Under these conditions peracetic acid is normally decomposed as rapidly as it is formed. Ill towers wetted with acetic acid and containing catalysts such as vanadium pentoxide, uranium oxide, roasted ferroso-ferric oxide, etc., the reaction between the aldehyde vapors and air tS"very rapid and complete, and temperatures as low as 30° to...
