Synthesis of Magnesium Oxide Nanomaterials Using Magnesium Carbonate as Precursors

Abstract:

Petaliform magnesium oxide nanomaterials were prepared by which the basic magnesium carbonate made from light burning powder of low grade magnesite were used as precursor. The XRD results indicated that aqueous magnesium carbonate changed to basic magnesium carbonate (4MgCO₃•Mg(OH)₂ •4H₂O) when heating temperature reached 95°C, the SEM confirmed that the morpholo_Zgy of basic magnesium carbonate (4MgCO₃•Mg(OH)₂•4H₂O) were petaliform, after calcinations the magnesium oxide with the same morphologies as precursors’ were obtained, simultaneously , the products with high activity (iodine value of 197mgI₂/g).
