Abstract

On heating amorphous Pb(Fe2/3W1/3)O3 ceramics, glass transition occurred at 35$0^{\circ}C$, crystallization at 394~420, 485~550 and 540~571$^{\circ}C$ (depending on the heating rates of 2.5~8$0^{\circ}C$/min), phase transformation at 680 and 73$0^{\circ}C$, and melting at 935$^{\circ}C$. A curve-fitting computer program was made using FORTRAN, based on a kinetic equation. Reconstructed thermograms (using the program) turned out to be very close to the measured DSC results for all the heating rates, with average deviation of only 4% at maximum.
