Synthesis and characterization of manganese ferrite from low grade manganese ore through solid state reaction route

Abstract Manganese ferrite spinel has been synthesized by using low grade manganese ore and ferric oxide as sources of manganese oxide and iron oxide through solid state reaction route by taking manganese and iron mole ratio of 1:2 respectively. The impact of sintering temperature on phase compositi...
