Abstract: Described herein is a process for making a nickel composite hydroxide with a mean particle diameter d50 in the range from 3 to 20 ?m including combining (a) an aqueous solution of water-soluble salts of nickel and of at least one of cobalt and manganese, and, optionally, at least one of Al, Mg, B, or transition metals other than nickel, cobalt, and manganese, (b) an aqueous solution of an alkali metal hydroxide and (c) an aqueous solution of alkali metal (bi)carbonate or ammonium (bi)carbonate in the molar ratio of 0.001:1 to 0.04:1, and, optionally, (d) an aqueous solution of alkali metal aluminate, in a continuous stirred tank reactor or in a cascade of at least two continuous stirred tank reactors.

Abstract: Process for precipitating a mixed hydroxide of TM wherein TM comprises Ni and at least one of Co and Mn and, optionally, Al, Mg, Zr or Ti, from an aqueous solution of salts of such transition metals or of Al or of Mg, wherein such process is carried out in a stirred vessel and comprises the step of introducing an aqueous solution of alkali metal hydroxide and an aqueous solution of transition metal salts through at least two inlets into said stirred vessel wherein the distance of the locations of introduction of salts of TM and of alkali metal hydroxide is equal or less than 6 times the hydraulic diameter of the tip of the inlet pipe of the alkali metal hydroxide.

Abstract: Provided are compounds of the formula MA1-xMBxXA1-yXByQA1-zQBz, wherein MA and MB are selected from Si, Ge, Sn, and Pb, XA and XB are selected from F, Cl, Br and I, QA and QB are selected from P, As, Sb and Bi, and x, y and z are 0 to 0.5, as well as doped variants thereof, useful as semiconducting materials. Due a double helix structure formed by the constituting atoms, the compounds are particularly suitable to provide nano-materials, in particular nanowires, for diverse applications.
