An investigation was made into the form of impurities like silicon,aluminum,calcium and magnesium present in the synthetic rutile mother liquor,which have some effects on the magnetic property of materials.By controlling pH value of the liquor and adding precipitation agent,a purified solution containing wSiO2 ≤ 16.7×10-6、wCaO<5×10-6、wMgO<5×10-6、wAl2O3<10×10-6 was obtained based on orthogonal and validation tests.Then the purified solution was roasted to prepare ferric oxide powder for soft-magnetic use which is consistent with the standard SJ/T10383-1993YHT2.
