Abstract
819,302. Retorts ; decomposing double salts ; beryllium fluoride. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 27, 1956 [Feb. 8, 1955], No. 3640/55. Classes 1 (1) and 1 (3). [Also in Group XII] A double salt, such as ammonium beryllium fluoride, which is liable to froth on thermal decomposition is scattered over the hearth of a retort heated at the bottom sufficiently to melt the solid formed by decomposition and at the roof to a higher temperature such that radiation from the roof will bring about decomposition of the double salt. In the described embodiment (see Fig. 1), a stainless steel ram 8 operating in a carbon-lined water-jacketed stainless steel tube 6 connected to a source of argon, is used to scatter ammonium beryllium fluoride after the hearth of a retort 1 lined with graphite rendered impervious by impregnation with a hydrocarbon followed by thermal cracking thereof. The retort is heated from below to 800-850 ‹ C. by means of gases passing through a lower heating chamber 3 and from above to 1200-1250‹ C. by means of burner gases in chamber 13 having a baffle 14. Alternatively, electrical resistance or induction heating may be employed. Molten beryllium chloride is tapped off into preheated moulds through stainless steel orifice 9a closed by carbon valve 9 whilst ammonium fluoride vapour is recovered in a condenser or scrubber for reuse in the production of further ammonium beryllium fluoride. The parts of the supporting structure 2 adjacent to the chambers and flues are made of molochite and the sheath 1a of the retort is protected where exposed by means of carborundum.
