摘要：Class F flyash sample is subjected to roasting both by conventional process as well as microwave technique.The phase change during roasting with microwave heating has been investigated by XRD method and the chemicalcomposition has been monitored continually by quantitative as well as AAS method. The results show that the flyashsamples couple well with microwave and the temperature can reach approximately 10000 C in 7 minutes. The phasechange in iron has been observed along with SiO2 and Al2O3. By proper control of the roasting temperature flyash canbe sintered into a reasonably strong and relatively porous glassy ceramic material in a short period of time usingmicrowave technique.
