Reduction of Beryllium Fluoride with Magnesium. The Schwenzfeier process (11) is used to prepare a purified, anhydrous beryllium fluoride [7787-49-7], BeF2, for reduction to the metal. Beryllium hydroxide is dissolved in ammonium bifluoride solution to give a concentration of 20 g/L... [Pg.67]

Beryllium fluoride [7787-49-7], BeF2, is produced commercially by the thermal decomposition of diammonium tetrafhioroberyllate [14874-86-3], (NH4)2BeF4. The fluoride and the fluoroberyllates show a strong similarity to silica and the silicates. Like silica, beryllium fluoride readily forms a glass,... [Pg.75]

Beryllium fluoride. [CAS 7787-49-7], BeF2, is readily soluble in water, dissolving in its own water of hydration as BeFo 2H2O. The compound cannot be crystallized from solution and is prepared by thermal decomposition of ammonium fluoberyllate. (NH BeF ... [Pg.197]

Beryllium. Beryllium [7440 41-7], Be, metal is produced by electrolysis of KQ—NaQ—BeQ2 melts. Temperatures up to 900°C are required. Cell voltages are 6 to 9 V (115). Electrolysis of mixtures of beryllium oxide [1304-56-9], BeO, in lithium fluoride [7789-24 4], LiF, and beryllium fluoride [7787-49-7], BeF2, has produced beryllium metal at about 700°C and 2.6 V (116). Details of fused salt metal winning processes are given in Table 7. [Pg.80]

Uses Beryllium (Be) (when pure) is a hard, grayish metal. In nature, beryllium can be found in compounds in mineral rocks, coal, soil, and volcanic dust. The important compounds of beryllium used in industry are beryllium oxide (BeO), beryllium hydroxide (Be(OH)2), beryllium sulfate (BeS04), and beryllium fluoride (BeF2). Beryllium compounds are commercially mined and purified for use in electrical parts, machine parts, ceramics, aircraft parts, nuclear weapons, and mirrors. Beryllium dust is emitted into the air from burning coal and oil. [Pg.65]
