To establish the crystal heating schedule of Plat-II castable ceramic materials. This study first identified the thermal limits of Plat-II castable ceramic crystallization basing on DTA exotherm analysis, then the crystal density of various heating schedule was observed by scanning electron microscope. The efficient crystal heating schedule of Plat-II castable ceramic was established: The temperature was increased from the room temperature to 620 degrees C with the speed of 10 degrees C/min, kept 20 min, then was increased continually to 670 degrees C with the speed of 5 degrees C/min, and kept 30 min. The establishment of the crystal heat treatment schedule of Plat-II castable ceramic will become the basis for the further study.
