The thermal decomposition of Al2(SO4)3.-nH2O and Hf(SO4)2.4H23 was studied in air by thermogravimetry and in vacuum by simultaneous thermogravimetry and evolved-gas analysis. No SO2 was detected by the mass spectrometer. The primary products of decomposition appear to be SO and O2 for both sulfates. For the Al salt, the Arrhenius relationship shows 2 activation energies, whereas for the Hf salt there is only 1 activation energy in vacuum and 2 activation energies in air. X-ray data show the solid products of the reactions to be η-Al2O3 and HfO2. The diffraction pattern for Hf(SO4)2.4H2O is presented.

Production of spherical particles of aluminum sulfate hydrates by using a prilling technique has never been studied, nor carried out. The effects of the orifice geometry and hydrostatic head on drop formation were measured. The flow rates of hydrated aluminum sulfate melt through bores of 0.08 and 0.11 cm were measured for liquid heads of 10-100 cm. It was found that the break-up of a liquid jet produced particles in the size range 2.0-2.5 mm with a 0.8 mm orifice. The modified Meister and Scheele correlation, which is the first application on a high viscous fluid in air system, was found to be satisfactory for estimating the particle size obtained by the jet break-up mechanism.
