摘要： Methods for synthesizing chalcogenide perovskites and chalcogenide perovskites synthesized thereby. Such s method includes providing a precursor solution containing a metal precursor, depositing the precursor solution onto a substrate to form a precursor film, and heating the precursor film in the presence of a chalcogen source to form a chalcogenide perovskite. The precursor solution is oxygen-free, and the steps of depositing and heating are conducted in an inert atmosphere.

摘要： A PROCESS IS PROVIDED FOR PREPARING ZIRCONIUM SULFATES BY FUSING A ZIRCONIUM SILICEOUS ORE, SUCH AS ZIRCON SAND, WITH AN ALKALI METAL CARBONATE OR HYDROZIDE TO FORM AN ALKALI METAL ZIRCONYLOSILICATE, AND/OR ALKALI METAL ZIRCONATE, AND SILICATE, WHICH IS DISSOLVED IN AQUEOUS HYDROCHLORIC ACID TO FORM A CLEAR SOLUTION OF ZIRCONYL CHLORIDE AND SILICIC ACID. AN AQUEOUS SULFATE SOLUTION IS ADDED, AND THE MIXTURE HEATED TO RPECIPITATE A ZIRCONIUM SULFATE. THIS CAN BE CALCINED TO FORM ZIRCONIUM OXIDE. IF FLUORIDE IS ADDED WITH THE SULFATE SOLUTION, A SERIES OF BASIC AND ACIDIC ZIRCONIUM FLUOSULFATES CAN BE OBTAINED USEFUL AS A GLASS POLISHING ADDITIVE. THE ZIRCONIUM FLUOSULFATES CAN ALSO BE CALCINED, TO FORM A VERY PURE ZIRCONIUM OXIDE. A PROCESS ALSO IS PROVIDED FOR PREPARING A ZIRCONIUM OXIDE HAVING A VERY LOW PROPORTION OF SILICA, BY CALCINING A ZIRCONIUM COMPOUND COMPRISING SILICA IN THE PRESENCE OF FLUORINE OR A FLUORIDE.

摘要： Metal-organic compounds or complexes are prepared by heating zirconyl carbonate with at least one monocarboxylic acid and further reacting with at least one divalent metal as a metal powder, oxide, hydroxide or carbonate, and distilling off the water formed. Calcium, strontium, barium, zinc, cadmium, magnesium, manganese, iron, nickel, cobalt, lead, mercury and copper are the metals and acetic, propionic, 2-ethyl hexoic, methacrylic, naphthenic, tall oil, or synthetic branched chain C8-C10 acids are mentioned. Additional acids may be alkyl or aryl phosphoric or phosphorous acid or sulphonic acids and phenols or alkyl phenols may be added to the reaction mixture and glycol or glycol ethers added to the product. The products have good compatability with organic media and may be used as driers, in surface coating compositions and as stabilizers for polymers, e.g. polyvinyl chloride.

摘要： A process for improving the grade and optical quality of zircon, comprising: baking a mixture of a zircon feed and concentrated sulphuric acid at a baking temperature in the range of from 200 up to 400° C., and for a time to form water leachable sulphates with impurities therein including at least iron and titanium; leaching the baked mixture to dissolve the leachable sulphates; and separating the zircon from the leachate containing the leached sulphates, which separated zircon is thereby of improved grade and optical quality.
