    摘要： According to the invention, an iron oxide is provided for ferrite having a Mn content of 0,1 to 0,3 % by weight and a P content of not more than 0,005 % by weight. Such an iron oxide can easily be produced by making an iron chloride solution, dephosphorizing the iron chloride solution by a simple process and oxidizing roasting the dephosphorized solution to provide the desired iron oxide. Although Mn is contained as an impurity the ferrite properties are not impaired thereby since attention is paid to the impurities of P which are at a low level. Accordingly, soft ferrite can be produced having excellent ferrite properties.

    摘要： A solution containing iron chloride and manganese chloride, whose phosphorus content is not higher than 0.007 wt.% with respect to the total content of iron and manganese. A method for producing the said solution comprises the steps of dissolving manganese containing raw material in hydrochloric solution; oxidizing the solution; adjusting the pH of the solution to 2.5 ∼ 4.5; separating the insolubles from the solution. This solution can be utilized to produce a mixed powder of an iron oxide and a manganese oxide. And the mixed powder is useful for producing a high-quality soft ferrite.
