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.

权利人:KILAMBI SRINIVAS; SRIYA GREEN MATERIALS INC
摘要:A method of making Portland cement, white cement, calcium aluminates, calcium aluminum silicates and similar oxides using solid state combustion synthesis is described. The method uses less energy and produces lower CO 2 emissions than conventional processes. The method uses green fuels like biomass and lignin and eliminates most of the coal used in traditional cement production. A batch reactor and a semi-continuous reactor that can be used for the combustion synthesis are also described.

摘要:A two-stage process for the production of m- or pphenylenediamine by chlorinating a dilute aqueous mineral acid suspension of the corresponding initial iso- or tere-phthalamide reactant in a first stage, the dilution being sufficient to retain hydrogen chloride being formed substantially completely dissolved in the reaction mixture, and then converting the N,N''dichloro-isophthalamide or N,N''-dichloro-terephthalamide intermediate product into the corresponding m- or pphenylenediamine in a second stage by reaction with an aqueous solution of an alkali or alkaline earth metal hydroxide. The diamine products are of known utility, especially as intermediates in the synthesis of azo dyes.

摘要:A method of making cementitious particles using combustion synthesis is described. The method uses less energy and produces lower CO 2 emissions than conventional processes. By controlling the process conditions, the morphology and the properties of the particles can be easily tuned for a variety of applications. A batch reactor and a continuous conveyor type reactor that can be used for the combustion synthesis with high viscosity raw materials are also described.

摘要:Cementitious compositions and methods of synthesis are disclosed. By decreasing the Ca-rich raw material in a cement composition, the content of Alite (Ca 3 SiO 5 ) per ton of produced cement can be mitigated. Alite is the most energy-intensive and most polluting component among cement ingredients. By decreasing this component, the process can potentially reduce the environmental footprint and energy consumption by as much as 12% per ton of cement. In one embodiment, the average Ca/Si ratio in hardened cement paste can be reduced from Ëœ1.7 to Ëœ1.5. This corresponds to about a 12% reduction in Alite content per ton of produced cement. The cement compositions can also be characterized as solid-state cement hydrates including a plurality of silicate chains, the plurality of silicate chains including a plurality of dimers constituting at least about 60% of the plurality of silicate chains present in the solid-state cement hydrate, the plurality of dimers enhancing the strength of the solid-state cement hydrate. Such solid-state cement hydrates can also exhibit a periodic molecular structure formed from the plurality of silicate chains, e.g., ring-like structures.
