Abstract
A method of manufacturing magnetic material is described hereinafter. Firstly, Fe(NO3)3.9H2O and other metal nitrate compounds are dissolved in an alcohol solvent to form a mixed solution. Secondly, the mixed solution is heated to 60˜100 degrees Centigrade. Next, citric acid is added into the mixed solution for being reacted with each other under the temperature of 60˜100 degrees Centigrade so that can make the alcohol solvent volatilized and further obtain brown solid powder. Lastly, the solid powder is further heated for a period of time so as to obtain the magnetic material having a fluffy powdery form.
