Synthesis of iron(III) oxide with controlled surface fractality

摘要: Mercury porometry is applied to measure the surface fractal dimension of iron(III) oxide samples prepared by thermolysis freeze-drying product iron(III)-ammonium oxalate. It shown that A s o l i d → B a + C g type topochemical reaction can in principle give rise fractality irop(III) oxide. The effect decomposition rate precursor salt and isothermal anneal duration on studied. new method proposed for synthesis with controlled dimension.
