The influence of the mass transfer phenomena on the thermal decomposition of calcium carbonate powders under vacuum was investigated through a detailed kinetic analysis by the constant transformation rate thermal analysis (CRTA). Reliable kinetic curves, free from the mass transfer problems, can be
## Abstract A quadrupole mass spectrometer coupled to a thermobalance has been used to develop a controlled rate thermal analysis (CRTA) equipment. This instrument maintains constant the partial pressure of the gas generated in a solidβgas reaction during the entire process while recording the weig
