文摘

After 500 °C sintering the cobalt ferrite shows complete crystallization. An inversion sintering temperature between 900 °C and 1200 °C is proposed where the Fe+3 again starts migration from B site to A site. Sintering temperature is one of the prime factors which effect the magnetization and cation distribution between two sites A and B.
