摘要:The present disclosure relates to a method for external synthesis of rare-earth oxychloride and production of rare-earth metal or alloy. The method comprises the steps of adding hydrochloric acid (HCl) to a portion of a pre-defined weight of rare-earth oxide (RE2O3) converting the portion of RE2O3 to rare-earth chloride hydrate (RECl3.xH2O). The method further comprises mixing the residual rare-earth oxide (RE2O3) with the RECl3.xH2O and heating the mixture to a temperature exceeding 300℃ to obtain rare-earth oxychloride (REOCl). The method includes making the obtained REOCl to react directly with a reductant or mixture of reductant and alloying element in a temperature of 600℃ - 1400℃ for reducing the rare-earth oxychloride (REOCl) to rare-earth metal or alloy; and upon cooling, treating the reduced mass of rare-earth metal or alloy with water and dilute acid to remove reaction byproducts such as calcium chloride (CaCl2) and calcium oxide (CaO).

摘要:The invention provides methods for a one-pot synthesis of molecular sieves of the CHA-type. The method uses molecular and non-molecular sieves as sources of silicon and aluminum. A first OSDA is selected from tetraethylenepentamine (TEPA) and triethy-lenepentamine (TETA). The synthesis mixture comprises a first metal selected from copper, iron and zinc. Optionally, the synthesis mixture may furthermore comprise a second OSDA and/or a second metal selected from manganese, cesium, magnesium, calcium, strontium, barium, yttrium, titanium, zirconium, niobium, iron, zinc, silver, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and mixtures thereof. The molecular sieves of the CHA-type obtainable by the method can be used as SCR-catalytically active substances for the removal of nitrogen oxides from exhaust gases of combustion engines.

摘要:Methods for the preparation of inorganic nanoparticles capable of fluorescence, wherein the nanoparticles consist of a host material that comprises at least one dopant. The synthesis of the invention in organic solvents allows to gain a considerably higher yield compared to the prior art synthesis in water. All kinds of objects can advantageously be marked and reliably authenticated by using an automated method on the basis of a characteristic emission. Further, the size distribution of the prepared nanoparticles is nartower which renders a subsequent size-selected separation process superfluous.

摘要:A novel process is described for the preparation of a microporous crystalline solid, known as IZM-2 microporous solid or IZM-2 zeolite. This novel process consists of carrying out the synthesis of IZM-2 zeolite by conversion/transformation of a zeolite with structure type FAU in a fluorinated medium under hydrothermal conditions. In particular, said novel process consists of carrying out the synthesis of an IZM-2 zeolite in a fluorinated medium starting from a zeolite with structure type FAU used as the source of silicon and aluminium and a specific organic molecule or template comprising two quaternary ammonium functions, namely 1,6-bis(methylpiperidinium)hexane dihydroxide.

摘要:The present disclosure provides a preparation method for hydrothermal synthesis of fly ash silicate aggregate including: mixing sodium metasilicate, potassium hydroxide, and inorganic-organic hybrid excitation monomer as raw materials to obtain an inorganic-organic composite activator; preparing a silicate aggregate raw material, mixing measured fly ash, carbide slag, quicklime, and vitrified micro bubble by mass, adding the inorganic-organic composite activator and continue stirring to produce a mixture; forming a ball disc, wetting an expanded perlite that forms a core of the ball by spraying water, adding a prepared mixture, spraying water while adding, standing and curing, performing a maturation and activation treatment in an autoclave, undergoing a silicon calcium reaction for a hydrothermal synthesis to obtain the silicate aggregates. The present disclosure obtains silicate aggregates with high-performance by accelerating an internal activity of fly ash at an early stage and fully activating the activity of fly ash in all process.
