• The thermal decomposition of lead carbonate tablets was kinetically studied in a nitrogen gas stream at temperatures of 240, 320, and 360°C. The tablets used in this work were prepared by compressing lead carbonate particles in a steel mold under pressures of 2–15 ton/cm<SUP>2</SUP>. The decomposition reaction for the tablet was represented in two ways. Rate expressions were developed from the unreacted-core shrinking model applied to the individual particles (for the first of the two decomposition processes) and to the whole tablet (for the second). The effect of the pressure applied in preparing the tablet on the decomposition rate was attributed to the deviation in the pressure profile for carbon dioxide in a tablet (for the first process) or to the variation in the effective diffusivity and bulk density of the tablet (for the second).
