Rate of cementite formation increase with temperature. At 750 °C and 800 °C, iron oxides are completely converted to cementite in only 15 minutes and the cementite formed is relatively stable. Increase in temperature from 800 °C to 850 °C and further to 925 °C accelerates the initial rate of cementite formation. Increasing temperature also increases the rate of cementite decomposition in the temperature range 750 °C to 925 °C. The rate of decomposition decreases with increasing temperature in the temperature range of 650 °C to 750 °C.
