硝酸铝[Al(NO3)3]是一种常用媒染剂。工业上用铝灰(主要含Al、Al2O3、Fe2O3等)制取硝酸铝晶体[Al(NO3)3·9H2O]的流程如下: ⑴ 写出反应Ⅰ的离子方程式: (任写一个)
铬是一种银白色金属 化学性质稳定,以+2、+3和+6价为常见价态。工业上以铬铁矿(主要成分为FeO·Cr2O3,含有Al2O3、SiO2等杂质)为主要原料生产金属铬和重铬酸钠(Na2Cr2O7·2H2O),其
The morphological changes accompanying the conversion of the hexagonal CaO·Al2O3·10H2O phase to the cubic 3CaO·Al2O3·6H2O phase were studied by scanning electron microscopy. The hydration and conversion reactions were monitored by X-ray diffraction analysis. From the micrographs, it was ...
硼及其化合物在工业上有许多用途。以铁硼矿(主要成分为Mg2B2O5·H2O和Fe3O4,还有少量Fe2O3、FeO、CaO、Al2O3和SiO2等)为原料制备硼酸(H3BO3)的工艺流程如图所示:
