摘要： The present invention provides a method for integrated utilization of a calcium chloride solution and CO2. In this method, with the calcium chloride solution and the CO2 being taken as raw materials, a water-soluble amine is added as an auxiliary agent to promote the occurrence of a mineralization reaction. As a result of crystallization following the reaction, calcium carbonate and a solution of a hydrochloride of the water-soluble amine are obtained. After the reaction is completed, the water-soluble amine is regenerated by subjecting a liquid phase resulting from separation to bipolar membrane electrodialysis, and dilute hydrochloric acid is obtained as a by-product at the same time. The method provides a novel perspective and approach to integrated utilization of calcium chloride-containing liquid waste and flue gas CO2. The water-soluble amine allows excellent mineralization, and the bipolar membrane electrodialysis enables excellent regeneration of the amine. By means of process regulation, a calcium carbonate product of high value with controlled morphology and particle size can be obtained. For applications equipped with a lime kiln and allowing recycling of calcium carbonate, such as the ammonia-soda industry, the present invention also provides a combined cycle process for carbon and calcium resources, in which calcium carbonate produced by a mineralization reaction is calcined in lieu of limestone used in the soda production process to provide the soda production process with CO2 and milk of lime, enabling recycling of carbon and calcium resources in an ammonia soda plant. The entire process is free of waste discharge, showing a promising prospect of application. It is of great significance to the fields of calcium chloride-containing liquid waste disposal and carbon emission reduction.

摘要： A process for recovering lithium chloride from a lithium sulfate (Li2SO4)-containing mixture is described, comprising a step of sulfate removal using barium chloride (BaCl2). In embodiments, the process may further comprise one or more steps to reduce the level of one or more metals other than lithium and to reduce the level of sulfate by increasing the pH of the (Li2SO4)-containing mixture, e.g., using a calcium salt. In embodiments, treatments to reduce the level of one or more metals other than lithium, sulfate, and other components (e.g., calcium if used) may be used, producing a solution substantially comprising Li2SO4 for barium chloride (BaCl2) treatment, to form a precipitate comprising barium sulfate (BaSO4) and a solution substantially comprising lithium chloride.

摘要： Inorganic particles comprised in an aqueous dispersion according to the present invention consist of agglomerates of crystalline and amorphous microparticles, and exhibit spherical and smooth surfaces. The spherical appearance, low crystallinity, and narrow particle size distribution of the inorganic particles are further advantageous in reducing scratch defects in a CMP process. In addition, since the microparticles on the inorganic particle surfaces provide more active sites and thus the removal rate is high, the inorganic particles may be advantageous as next-generation CMP polishing materials. In addition, the aqueous dispersion according to the present invention further comprises an amino acid, and the amino acid may be adsorbed on a surface of a silicon oxide wafer to strengthen electrostatic attraction between the silicon oxide wafer and the inorganic particles, resulting in an effect of further improving the removal rate.

摘要： The present application pertains to processes producing oxides using a weak acid intermediate. In one embodiment a material comprising calcium carbonate is reacted with a solution comprising aqueous carboxylic acid to form a gas comprising carbon dioxide and a solution comprising aqueous calcium carboxylate. The solution comprising aqueous calcium carboxylate is reacted with sodium sulfate to form a solution comprising aqueous sodium carboxylate and a solid comprising calcium sulfate. The solution comprising aqueous sodium carboxylate is reacted with sulfur dioxide to form sodium sulfite and an aqueous carboxylic acid. The sodium sulfite is separated from said aqueous carboxylic acid and reacted to form a solid comprising calcium sulfite which is decomposed to form calcium oxide and sulfur dioxide.

摘要： A method for manufacturing a fused metal sight window that melts the metal of the frame around the window, instead of the traditional method of melting the window into the frame. Since most of the superior optical transparent materials (such as fused silica, sapphire, YAG, ALON, diamond, fused quartz and magnesium fluoride) have a melting point higher than most metals, it was not previously possible to create fused metal sight windows with these materials. By melting the frame onto the window, many new combinations of metals and optical materials may be used while retaining the strength of the sight window that results from fusing the metal and the window.
