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).

本实验根据X-射线衍射仪分析钛铁矿组成和结构的结果，利用钛铁矿显著吸收微波的介电特性，使用改装后的800W家用微波炉，在常压下选择中低火加热温度（160℃左右），分别用磷酸和磷硫混酸在微波辐照下消解粒度小于0.125mm的矿样，可快速将矿样消解完全。
