Fist-order reversal curve Study on Calcined Indian Redmud

The present work deals with redmud were calcined at different temperatures ranging from 30℃ and 1000℃ for 1 hour in furnace and characterised by First order reversal curve (FORC). The magnetic hysteresis parameters as a function of temperature were determined from the FORC curves. The test results indicate good reactivity was observed till a temperature of 900℃, after which it started declining.
