权利人:COUNCIL SCIENT IND RES
摘要:The present invention relates to a single step process for the synthesis of nanoparticles of phase pure ceramic oxides of a single or a multi-component system comprising one or more metal ions. The process comprises preparing a solution containing all the required metal ions in stoichiometric ratio by dissolving their respective soluble salts in an organic solvent or in water, preparing a precursor, adjusting the nitrate/ammonia content in the system, and heating the system.

摘要:The present invention relates to a method for upgrading silicon-containing solid residues obtained after leaching of copper from copper-containing residues from direct synthesis of organochlorosilanes. Solid residue, optionally together with an oxidation agent, is supplied to a smelting furnace where the residues are melted and form a molten metallic phase substantially containing silicon and a calcium silicate slag and tapping of the molten metallic phase and an inert slag from the smelting furnace.

摘要:Mesoporous calcium silicate compositions for controlled release of bioactive agents and methods for producing such compositions are disclosed herein. In one embodiment, mesoporous calcium silicate is synthesized by acid modification of wollastonite particles using hydrochloric acid. A hydrated silica gel layer having abundant Si—OH functional groups can be formed on the surface of wollastonite after acid modification. Bruhauer-Emmett-Teller (BET) surface area increased significantly due to acid modification and, in one arrangement, reached over 350 m 2 /g. Acid modified mesoporous calcium silicate compositions show a higher ability to adsorb protein compared to unmodified particles and demonstrate controlled release kinetics of these proteins.

摘要:In some aspects, the present disclosure pertains to methods for the electrochemical production of calcium silicate compounds in an electrochemical cell that comprises (a) a Ca-based electrode that comprises calcium metal or an inorganic calcium material, (b) an SiOx-based electrode that comprises a SiOx material, where x ranges from 1 to 2, and (c) a liquid electrolyte disposed between the Ca-based electrode and the SiOx-based electrode. In these methods, the electrochemical cell is operated under conditions such that calcium cations are produced at the Ca-based electrode and one or more calcium silicate (Ca—Si-oxide) compounds are produced at the SiOx-based electrode. In other aspects, the present disclosure pertains to systems for the electrochemical production of calcium silicate compounds.
