摘要： Aluminum chloride hexahydrate is thermally decomposed to alumina by sequential treatment in two dense fluidized-bed decomposers, the first decomposer being operated at a temperature of about 200 to 400°C and the second at a temperature of about 900 to 1100°C. About 90 to 95 percent decomposition is achieved in the first decomposer, with substantially complete decomposition of the remainder in the second decomposer. Fluidization in the first decomposer is preferably achieved by means of recycle of product gases.
摘要翻译：氯化铝六水合物通过在两个致密的流化床分解器中顺序处理而热分解成氧化铝，第一分解器在约200-400℃的温度下操作，第二分解器在约900℃至1100℃的温度下操作在第一分解器中实现约90至95％的分解，其余部分基本上完全分解在第二分解器中。第一分解器中的流化优选通过产物气体的再循环实现。

摘要： Method for the decomposition of aluminum nitrate crystals to alumina comprising the steps of: (a) melting the aluminum nitrate crystals; (b) evaporating from the melted crystals in a once through evaporator at the boiling temperature of the mixture and for a time sufficient to remove water and associated nitric acid and to provide a fluid having an alumina concentration of at least about 18% by weight; (c) decomposing the product of step (b) at a temperature of between about 150 and about 200`C and recovering the heat of condensation of the resultant vapors; (d) further decomposing the product of step (c) in a fluidized bed decomposer at a temperature of between about 300 and about 400`C to reduce the residual nitrate concentration in the product to between about5 and about 10 weight percent; (e) decomposing the product of step (d) in a fluidized bed decomposer at a temperature of between about 500 and about 800`C to reduce the residual nitrate concentration in the product to below about 3 percent by weight; and (f) calcining the product of step (e) at a temperature of at least about 1000`C.

摘要： A method of making materials using gas coupled with vapor phase transport. One embodiment of the method includes the steps of providing a reaction mixture including a plurality of reactive chemical species capable of reacting exothermically and heating the mixture in an environment including a reactive gas such that the plurality of reactive chemical species will react, wherein sufficient heat is generated from an exothermic reaction between the plurality of reactive species to generate a volatile intermediate reaction species which subsequently reacts to form the at least one chemical product. In another embodiment, the reaction mixture, reactive gas and vapor phase transport are employed in the presence of a nucleating agent to produce a desired product form. The materials include ceramics, metals, and combinations thereof in varying morphologies, including fine particles (32c), whiskers (32a and 32b), hollow shells, platelets and combinations thereof, and composite materials containing the same which have been synthesized in situ.
