SURFACE AND STRUCTURE STUDY OF CLAY-BASED COMPOSITES AFTER THERMAL TREATMENT
The composite materials prepared from clay and iron oxides in different weight ratios and temperatures denoted as A85 and E20 were heated at 300 °C in reductive atmosphere and up to 650 °C in inert atmosphere. The changes in the structure, surface and pore properties were examined by XRD, N2 adsorption method and TG, DTA method. The morphology was ...
