Ferrous fluoride

Iron Tantalates.—The meta-salt, Fe0.Ta206, has been obtained more or less pure by fusing tantalum pentoxide and ferrous fluoride with excess of potassium chloride.8 Iron tantalates occur naturally in niobites and tantaMtes. The ore tapiolite has the approximate composition FeO.Ta2Os the tantalum may be partially substituted by niobium.9... [Pg.200]

Ferrous fluoride, FeF2, may be obtained as colourless monoclinic crystals of density 4 09 by heating reduced iron or anhydrous ferrous chloride to redness in a current of dry hydrogen fluoride.2 In the amorphous condition it results on passing hydrogen fluoride over ferrous chloride in the cold. [Pg.87]

Crystals of magnetic oxide have been obtained in a variety of ways, such as by calcination of sodium carbonate and ferrous chloride 1 by fusion of potassium sulphate and iron phosphate 2 by the action of hydrogen chloride upon heated ferrous oxide 3 and by ignition of ferrous fluoride with boric anhydride.4... [Pg.113]

Cobalt difluoride [10026-17-2] C0F2, is a pink solid having a magnetic moment of 4, 266 x 10 J/T (4.6 Bohr magneton) (1) and closely resembling the ferrous (Fep2) compounds. Physical properties are Hsted in Table 1. Cobalt(II) fluoride is highly stable. No decomposition or hydrolysis has been observed in samples stored in plastic containers for over three years. [Pg.178]

Dissolution occurring to belong to protonation involves the processes highlighted out in Table 5.2. The dissolution of calcium carbonate in acids, the decomposition of calcium fluoride by concentrated sulfuric acid, the dissolution of ferrous sulfide in hydrochloric acid are some of the examples that can be pointed out as protonation-based dissolution. [Pg.475]

Calcium fluoride occurs in nature as the mineral fluorspar or fluorite. It is used as a flux in ferrous metallurgy to enhance the fluidity of the slag. An important application of this compound is in the manufacture of fluorine and hydrofluoric acid, starting materials for producing many fluoroorganics. It also is used in glass and ceramics. Pure crystals are used in lasers, optics, and electronics. Other applications are in high temperature, dry-film lubricants ... [Pg.164]

Ferrous Niobium Fluoride, 2NbF5.3FeF2.4HF.19H20 or NbaFe3F16. 4HF.19H20, is obtained in greenish-yellow, thin prisms by dissolving iron and niobic acid in equivalent proportions in hydrofluoric acid. [Pg.145]
