Abstract: Method for removing cadmium from phosphoric acid by the use of the permeation process through a liquid membrane. The method is comprised of: a) formulating an emulsion of the aqueous-in-organic type wherein the dispersed aqueous phase is the re-extraction phase and the organic phase contains an extraction agent of formula (I) wherein R1 and R2 are aliphatic, arylic or aromatic radicals and n can be simultaneously 1 or 0; b) dispersing said emulsion in a phosphoric acid solution; c) removing the aqueous phase which contains the cadmium-free phosphoric acid; and d) breaking the cadmium-laden emulsion to recycle the extraction agent. The obtained phosphoric acid may have a cadmium content of 1.5 ppm and may be used in the production of fertilizers. A preferred emulsion contains bis (2,4,4-trimethylpentyl) monothiophosphinic acid as agent for the selective extraction of cadmium.

Abstract: A process for preparing alloy products powders is described using a self-sustaining or self -propagating SHS-type combustion process. Binary, ternary and quaternary alloy having cadmium, selenium and optionally a third element X or Y selected from Group VIA (such as S or Te) or from group IIB (such as Zn or Hg). The alloy products may be doped or not with a wide variety of other elements. The process involves heating to ignition, maintaining an elevated temperature less than melting for homogenization, followed by cooling and crushing An optional de-oxidation process may follow to further purify the alloy and balance the stoichiometry.

Abstract: There is presented an n-type semiconductor which may be useful as a TCO material : gallium doped zinc cadmium oxide (which may be interchangeably referred to as: Ga-doped ZnCdO) with the general formula Zn 1-x-y Cd x Ga y O, where x and y may in a particular embodiment be given by, e.g., 0.05
