    Abstract: Ferrochrome alloy is mainly produced in submerged-arc furnaces. The reductants used in ferrochrome production include coke, anthracite and char. During ferrochrome production reductants are primarily added for reduction to take place. However it is still questionable as to what happens during times when the carbon charged is not enough, is stoichiometric or excess than the required amount. This work investigated phase formation and phase changes at different reducing temperatures with stoichiometric amount of reductants with stoichiometric amount of reductant. Experiments were conducted at 1200oC, 1300oC and 1550oC. Anthracite and coke were used in this investigation. A comparison of reaction steps, the extent of reactions as well as the mechanisms at the same temperature and soaking time, when coke and anthracite were used are discussed. The characterization was conducted using different analytical techniques to identify the changes in morphologies of the raw materials against the temperature as well as the phases that formed.
