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¡æ, after which it started declining. %K Redmud %K Coercivity %K Different Temperature %U http://article.sapub.org/10.5923.j.ijmc.20120204.01.html
