Abstrakt		The thermal behaviour of piroxicam (white anhydrous form) and its surface deposit (50 wt.%) on amorphous silicon dioxide was studied using TG and DSC techniques. On the basis of isothermal TG, thermal decomposition kinetic data were obtained and renetion mechanisms were established according to Sharp's method. It was tound that the thermal decomposition of pure piroxicam was heterogeneous, but that the surface deposit decomposed homogeneously throughout the whole reaction.
