Sažetak
The transformation kinetics of calcium oxalate trihydrate and calcium oxalate dihydrate to the thermodynamically stable monohydrate have been studied in batch precipitation systems. A combination of size distribution measurements, optical microscopy, X-ray diffraction and thermogravimetric analysis were used to characterise the processes involved. The transformation appears to be a solution mediated process in which dissolution of the unstable phases is followed by growth of the monohydrate ; corresponding dissolution and growth rates have been determined. The distribution of hydrates in the initial stages of the precipitation was very sensitive to the mixing process ; for example the use of a magnetic stirrer produced a different distribution to that formed with a propeller agitator.
