Abstract  

Mechano-chemical activation is a widely used method for increasing the reaction activity of solids and, consequently, to accelerate solid phase reactions and to reduce the temperature of the subsequent thermal decomposition. Thermal decomposition of triboactivated calcium carbonate is a subject of different studies while dolomite decomposition has limited data. The present work represents a study of thermal stability and phase transitions of mechano-chemical activated dolomite under different conditions, namely using various amounts and kind of milling balls and the duration of activation. Temperatures of decomposition of MgCO3 and CaCO3 are specified. The study includes the determination of the thermal stability and the rate of thermal decomposition of activated dolomite.

, 11 ]. Based on our studies, we can conclude that the use of low-molecular-mass glycols, ranging from ethylene glycol (EG) to hexane-1,6-diol (HDO), during PU glycolysis allows obtaining glycolysates with such chemical structure and thermal stability

Abstract  

Zeolites chemically modified with 1, 4 or 6 M aqueous solutions of NaOH were studied by DTA, TG and ETA (emanation thermal analysis) in the temperature range 201–200°C. The structural changes in the modified zeolites at room temperature and in the modified zeolites annealed at 1000°C were studied by XRD analysis. Thermal analysis demonstrated dehydration, dehydroxylation, structural changes and a glass transition. A gradual loss in crystallinity of the chemically modified zeolites was also observed. XRD analysis revealed structural changes caused by chemical treatment and also by annealing.
