采用可控双射流沉淀法，在硝酸铜存在下水解尿素，合成了化学计量量为Cu-2(OH)(3)NO3的羟基硝酸铜，类似于层状双氢氧化物族。特别关注了颗粒的大小、形态和团聚倾向。本工作的目的是根据回收产品的质量和分散性确定最佳沉淀条件。这种类血小板颗粒可作为纳米复合材料的各向异性填料。研究了反应物溶液的流量、浓度、反应器的设计和添加生长调节剂等反应参数。(C) 2003 Elsevier -Science B.V.版权所有
A copper hydroxynitrate of stoichiometry Cu-2(OH)(3)NO3, analogous to the layered double hydroxide family, was synthesized by the so-called controlled double jet precipitation technique, and by hydrolysis of urea in the presence of copper nitrate. Special attention has been focused on the size, morphology and agglomeration tendency of the particles. The aim of this work is to define the optimum precipitation conditions in terms of quality and dispersability of the recovered product. Such platelet-like particles Can be used as anisotropic fillers in nanocomposite materials. Several reaction parameters such as flow and concentration of the reactant solutions, design of the reactor and addition of a growth modifier were studied. (C) 2003 Elsevier -Science B.V.
