摘要： The present invention relates to a modified form of alumina hydrate filler, thermosetting and thermoplastic compositions having improved workability and mechanical properties containing such filler and methods of manufacturing such modified alumina hydrate filler. More specifically, the invention provides for the admixture of modified alumina hydrate crystals with a resinous composition in which the individual alumina hydrate crystal edges are substantially rounded, have a mean crystal size of less than about 35 microns and less than about 0.1% by volume of alumina hydrate crystals have a diameter of less than 2 microns. The resulting compositions have improved viscosity properties and exhibit good bending strength and flame retardant characteristics.

摘要： Synthetic crystalline aluminosilicate is prepared by an inorganic process from a reaction mixture, which contains, in an aqueous alkaline medium SiO.sub.2 and Al.sub.2 O.sub.3 or their hydrated derivatives or alkali silicates and aluminates, mineralizers and optionally seeding crystals, the reaction mixture containing: SiO.sub.2 /Al.sub.2 O.sub.3 in molar ratio of 15-40, OH.sup.- /SiO.sub.2 in molar ratio 0.1-0.2, and H.sub.2 O/SiO.sub.2 in molar ratio 20-60. The aluminosilicate produced by the process has a chemical composition expressed in molar ratios as: 0-3 M.sub.2 O:Al.sub.2 O.sub.3 :15-40 SiO.sub.2 :0-40 H.sub.2 O, where M represents an alkali cation. The aluminosilicate is useful in the preparation of catalysts and adsorbents.

摘要： A method of recovering fluorine, e.g. as hydrogen fluoride, from wastes of aluminum electrolysis furnaces, chemisorbents, adsorbents or absorbents, etc. in which the fluorine-containing material is subjected to pyrohydrolysis in an expanded fluid bed and the HF-containing gas is subjected to condensation or scrubbing for the removal of the HF therefrom. According to the invention, the exhaust gases from the fluidized bed are cooled by direct contact with solids which can be circulated in a separate cycle and are themselves cooled in a cooler, e.g. by contact with gas which is to be fed to the expanded fluidized bed. The circulated solids thus allow recovery of the sensible heat of the gas without diluting it.

摘要： A process for obtaining pure aluminum oxide (Al.sub.2 O.sub.3) from siliceous aluminum ore is disclosed. The aluminum ore is digested in a hydrochloric acid solution to obtain aluminum chloride, the aluminum chloride is crystallized as the hexahydrate, the aluminum chloride hexahydrate is purified and, subsequently, decomposed to give pure aluminum oxide and secondary products. The mother liquor of the crystallization step and the secondary products of the decomposition step are recycled.
