Abstract: Composite powder for use in an anode of a lithium ion battery, whereby the particles of the composite powder comprise silicon-based domains in a matrix, whereby the individual silicon-based domains are either free silicon-based domains that are not or not completely embedded in the matrix or are fully embedded silicon-based domains that are completely surrounded by the matrix, whereby the percentage of free silicon-based domains is lower than or equal to 4 weight % of the total amount of Si in metallic or oxidized state in the composite powder.

Abstract: The invention concerns alloyed zinc powders for alkaline batteries and a method to manufacture such powders. The powders are characterized by the presence of particles pierced with at least one hole. This appears to benefit the high drain discharge capacity while preserving the process ability of the powder, and the shelf life and the gassing behavior of the batteries. The invented powders can be manufactured using centrifugal atomization in a cooled, oxygen-depleted atmosphere.

Abstract: The present invention relates to doped ceria (CeO2) abrasive particles, having an essentially octahedral morphology. Such abrasives are used in water-based slurries for Chemical Mechanical Polishing (CMP) of subrates such as silicon wafers. The invention more particularly concerns yttrium-doped ceria particles having a specific surface area of 10 to 120 m2/g, characterized in that at least 95 wt %, preferably at least 99 wt %, of the particles are mono-crystalline and in that the particles' surfaces consist of more than 70%, preferably of more than 80%, of planes parallel to {111} planes. A novel gas phase process for synthesizing this product is also disclosed, comprising the steps of providing a hot gas stream, —and, introducing into said gas stream a cerium-bearing reactant, a dopant-bearing reactant, and an oxygen-bearing reactant, —the temperature of said gas stream being chosen so as to atomize said reactant, the reactant being selected so as to form, upon cooling, doped ceria particles.

Abstract: This invention relates to centrifugal atomized zinc alloy powders for alkaline batteries consisting of (a) 0.005-2% by weight of indium, and 0.005-0.2% by weight of either one of Al and Bi, or (b) 0.005-2% by weight of indium, and 0.005-0.2% by weight of Bi, and 0.001-0.5% of either one or both of Al and Ca, or (c) 0.005-2% by weight of either one or both of Bi and Al, and 0-0.5% by weight of Pb, the remainder being zinc. The powder is obtained by centrifugal atomisation in a protective atmosphere, where the oxygen content is less than 4% by volume. The resistance to corrosion in the electrolyte of the battery, especially after partial discharge, is markedly better than when the same alloys are prepared by the traditional production process. The capacity of batteries containing these powders is very good.

Abstract: The alloy is free from cadmium and it contains 0.001-1% In, 0.005-1% Mn and possibly up to 1% Pb, 0.005-1% Al and/or 0.0005-0.1% REM, REM being a rare earth metal or a mixture of rare earth metals. These alloys have a sufficient mechanical strength and resistance to corrosion and are easy to be processed.

Abstract: A zinc base powder for alkaline batteries consisting of 0.005-2% aluminum, 0.005-2% lead, 0.003-2% bismuth and 0.001-2% indium, the rest being zinc and unavoidable impurities.
