The paper presents research results on dehydration properties and thermal behaviour of zeolites synthesized from fly ash,
applying TG (thermogravimetry), DTG (derivative thermogravimetry) and SDTA (simultaneous differential thermal analysis) methods.
In result of the analysis conducted water contents in zeolite samples were defined. On the basis of the data obtained from
the thermogravimetric analysis, thermal behaviour of zeolites was assessed.
