A method for producing a magnetic powder includes the steps of: mixing neodymium oxide, boron, and iron to prepare a first mixture; adding and mixing calcium to the first mixture to prepare a second mixture; mixing an alkali metal with the second mixture to prepare a third mixture; and placing a carbon sheet on the third mixture, placing silica sand (SiOsand) thereon, and then heating the same to a temperature of 800&#xb0; C. to 1100&#xb0; C.

The present invention relates to a method for quantitatively analyzing Cl, remaining after synthesis, in zinc ferrite synthesized using chloride precursors such as zinc chloride and iron chloride, and provides a method capable of using, in a quantitative analysis method of Cl remaining after synthesis of an inorganic material, AQF-IC, which has been used only in the quantitative analysis of an organic sample since gaseous Cl, discharged after burning zinc ferrite in an automatic quick furnace (AQF) by using an Sn capsule and tungsten oxide (WO3), is analyzed through ion chromatography (IC).
