Abstract

The increasing need for reference materials in the field of low surface area adsorbents (such as pigments, fillers, medicinals...) made it necessary to launch a campaign for selecting and characterizing a set of 7 adsorbents (0.1 to 10m**2g**-1). The necessary selection of standard and reproducible outgassing conditions was carried out using the method of Controlled Reaction Rate Thermal Analysis (CRTA) associated with vacuum TG. The sensitivity and relevance of this method is illustrated here (especially for 2 samples losing less than 0.03% of their initial mass up to 500 degrees C) and the detection of small structural changes (for an alumina and a bronze) is commented on.
