Abstract
The thermal decomposition of a sol-gel precursor of Pb(Zr, Ti)O-3 is s tudied by thermogravimetric analysis-Fourier transform infrared spectr oscopy in argon and in air. It is found that in an inert atmosphere th e presence of residual carbon inhibits the formation of the perovskite structure. In air the evolution of volatile compounds such as alcohol s, esters, ethers and CO2 at temperatures above 300 degrees C indicate that polymerization is still going on during the thermal decompositio n of the precursor.
