Highly stable, homogeneous zirconia xerogels and ceramics were prepared from PZOs obtained by chelation of ethyl acetoacetate (Hetac) or acetylacetone (Hacac) to zirconium. The structure of PZO was analyzed by 1 H NMR. The thermal behavior of zirconia xerogels and ceramics were also determined by thermogravimetric/differential thermal analysis (TG/DTA), Fourier transform-infrared (FT-IR) spectroscopy...
The thermal decomposition of the complex of Schiff base containing S,N-Cd 3 [CH 3 O(O)C 6 H 3 CH = NNHC(S)NH 2 ] 4 .(CH 3 COO) 2 .1[CH 3 S(O)CH 3 ] . 2H 2 O and its non-isothermal kinetics have been studied by TG and DTG. The non-isothermal kinetic data were analyzed and the kinetic parameters for the first, second...
