Abstract: The present invention provides a process for the production of aluminum chloride and alumina of metallurgical grade purity, and valuable by-products from aluminous ores like clay, bauxites and laterites. The process comprises carbo-chlorination of the ore to produce aluminum chloride and other metal chlorides. The aluminum chloride is separated, purified and utilized as such or oxidized to make alumina while the other metal chlorides are processed to recover maximum values.

Abstract: A process for the production of silane in a reaction vessel comprising (i) a single closed chamber, (ii) a hollow tube open at both ends, said tube being disposed in the lower portion of the chamber; and (iii) means for circulating liquid in the lower portion of the chamber in such a manner that the liquid flows in a downward direction through the tube and in an upward direction outside of the tubeComprising the following steps:A. maintaining a melt of lithium chloride in the lower portion of the chamber, the level of the melt being above the tube;B. activating the circulating means;C. introducing liquid lithium into the melt in such a manner that at least a part thereof is brought to the surface of the melt;D. introducing hydrogen gas above the surface of the melt in such a manner that hydrogen gas reacts with lithium at the surface of the melt to form lithium hydride,The lithium, lithium hydride, and melt being admixed by the circulating means to provide a homogeneous mixture thereof;E.

Abstract: Fibrous alkali metal titanate is prepared by mixing 5-50 mole % of an alkali metal titanate or an alkali metal titanate forming components with a flux of an alkali tungstate or molybdate, and heating the mixture at 700.degree.-1,350.degree. C to grow the fibrous product in the molten flux mixture.

Abstract: An improved method is disclosed for producing aluminum chloride by contacting aluminum oxide, a reducing agent, and chlorine in a molten bath of aluminum chloride and metal halide to form aluminum chloride which is recovered from the bath by sublimation. The improvement comprises increasing the rate of formation of aluminum chloride by adding a source of metal selected from the group consisting of iron, chromium, copper, europium and cerium to the molten bath.

Abstract: A method for producing aluminum chloride comprises contacting Al.sub.2 O.sub.3 with a reducing agent and chlorine in a bath of molten metal halides to form aluminum chloride and recovering the aluminum chloride by vaporization.

Abstract: A process is disclosed for the preparation of arsenic trifluoride which comprises reacting arsenic trichloride with one or more molten fluoride salts.

Abstract: A low temperature method of producing boron trichloride comprises reacting an oxide of boron and a reducto-chlorinating agent in a molten bath comprising a combination of metal chlorides having a melting point of not more than 600.degree. C, to form boron trichloride, and recovering the boron trichloride by vaporization from the bath.
