Rifat Kamarudheen, Gabriel W. Castellanos, Leon P. J. Kamp, Herman J. H. Clercx. The thermal decomposition of the acetates of calcium, sodium, silver and copper(II) have been investigated using thermogravimetry and differential thermal The results indicate that the major organic product formed is either acetone or acetic acid, depending on whether the final solid product is the oxide or the metal. A modified autocatalytic expression was found applicable and a theory was postulated which lead to the correct algebraic relation.

A change of activation energy is thus compensated by the same change in temp. NiF The activation energies for both acceleratory and decay coeffs. on the kinetic equation are stressed.

Using an environmental scanning electron microscope, this result could be attributed to differences in nucleation rates at edges and faces of the single crystals.

Thermal decomposition of silver acetate was studied (TG, DSC, mass-spectrometry, X-ray analysis, electron microscopy). The resulting exponents become dependent on the system geometry and are further altered by the system nonideality due to the particles polydispersity, nonregular shapes, nonequal distribution, etc. as well as term definition reasons, compensation in this type of heterogeneous process is often artifactual and, therefore, cannot provide information of mechanistic value. of more than 110 substances from 20 different classes of solids: metals, non-metals, oxides, hydroxides, sulfides, selenides, tellurides, nitrides, azides, carbides, borides, fluorides, chlorides, bromides, iodides, carbonates, nitrates, sulfates, oxalates and hydrates.

It is concluded that H2O accelerates the solid-state reaction and escape of this product is opposed by the presence of an effective barrier phase of anhyd. decomposition process.
