METHOD AND APPARATUS FOR PRODUCING CRYSTAL GRADE ANHYDROUS RARE EARTH HALIDES
The invention relates to a method for producing crystal grade anhydrous rare earth halides, comprising the steps of melting an oxyhalide-free anhydrous NH4X/REX3 mixed salt, wherein X = C1 or Br, and RE is selected from the group consisting of Y, La and lanthanides, passing the melt through a carbon adsorbing filter, and allowing the melt to solidify in a mold, wherein all process steps are performed under inert gas flow. The molded rare earth halides obtained are carbon free and allow easy handling.
The invention relates to a method for producing a hard metal body, a powder for producing the hard metal and a produced hard metal body. According to the invention, said hard metal body consists of a hard material phase containing 60 mass % to 100 mass % WC and upto 40 mass % of a carbide, nitride, carbonitride or oxicarbonitride and at least one of the metals Ti, Zr, Hf, V, Ta, Cr, Mo, and one binding phase containing Co or a Co-alloy having upto 50 mass % of Ni, Fe or Cr, which constitutes 4 to 20 mass % of total hard metal. According to the invention, at least 10 vol. % of the WC is obtained by reacting a ternary W-Co-C-phase with carbon, said ternary W-Co-C-phase containing, in the dissolved form, prior to sintering, at least two of the metals Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, Fe, Ni, Sc, Y, La, Ce, Re, Ru, Rh, Pt.

The invention is directed to a process for the manufacture of a ceria based polishing composition, comprising (a) suspending an inorganic cerium salt or cerium hydroxide with a cerium content calculated as cerium oxide in the range of 50%-100% based on Total rare earth oxide (TREO) in an aqueous medium thereby obtaining an aqueous suspension, (b) treating said aqueous suspension with an acid or a salt of an acid selected from the group of HF, H3PO4 and H2SO4, thereby obtaining a solid suspended in said aqueous medium, (c) separating said solid from said aqueous medium, and (d) calcining the separated solid at a temperature between 750°C and 1,2000C and grinding the calcined solid to grain sizes in the range of 0.5 騜m to 5.0 騜m.
The claimed metal hydride reservoir in the form of a pressure vessel (1) has at least one gas pipe (7) for supplying or discharging gaseous hydrogen and at least one inner container (2) which is arranged in its inner chamber (3) and contains a hydrogen storage material. The metal hydride reservoir is characterised in that at least one inner container (2) comprises two parts interconnected by a gas-permeable filtering medium in such a way that hydrogen but not the hydrogen storage material can flow from the inner container into the inner chamber of the metal hydride reservoir and vice-versa.
A method of removing arsenic and heavy metals from water using metal salt hydroxidegels is provided. The arsenic present in water is adsorbed onto the hydroxide-gels which can effectively be filtered through a diatomaceous earth (DE) filtration bed. The combination of DE mixed hydroxide-gels is also effective in removing arsenic from water and heavy metals from water.
