Acording to the results for the analysis of component and structure of titanic iron ore with X-ray diffractometer and the fact in that titanic iron ore is prossessed of a dielectric property capable to absorb evidently microwave, a household microwave oven with power of 800W is applied to the decomposition of titanic iron ore sample under atmospheric pressure. It is shows that the sample with size of below 0.125nm can completely decomposed with phosphoric acid or mixture of phosphoric acid and sulfuric at about 160℃(corresponding to mid-low fire gear in microwave oven).
