Research of the morphology of MgO and its precursors with the liquid-phase method
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 3
Abstract
Based on the characteristics of solution homogeneous nucleation and the influence factors on crystal growth, different morphological magnesium carbonates (whisker, ellipsoid, sphere, rod, shell and leaf like) are respectively prepared by a solvent-induced method (ethylene glycol, triethanolamine as induced solvents) and a template-mediated method (cetyltrimethylammonium bromide as template agent). And using the obtained magnesium carbonate as precursors, magnesium oxides with the same morphologies as precursors’ are prepared by controlling the calcinations regulation. The morphology relations between magnesium oxide and its precusors are also further studied.
