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:
