Filed: 1982-04-30
Abstract: PURPOSE:To facilitate ferrite reaction and decrease heat energy required for calcination, by a method wherein an iron oxide which is mixed and adjusted to include specified amount of Fe<2+> is used as starting material. CONSTITUTION:An iron oxide as main starting material is mixed with iron oxide including Fe<2+> in 0.5-75% or iron oxide including Fe<3+> as main component and Fe<2+> so that amount of included Fe<2+> is adjusted to 0.5-75%. As the calcination reaction progresses, Fe<2+> in iron oxide as a raw material is oxidized and finally becomes Fe<3+>. During this process, various ferrite compounds including Fe<2+> are formed and have effect of filling material thereby the reaction is accelerated. Oxidation heat produced when Fe<2+> is oxidized into Fe<3+> is also effective. Optimum value of amount of Fe2+ in iron oxide as starting material is dependent on oxygen partial pressure and oxygen flowing amount in a calcination apparatus such as rotary kiln or drying furnace.
