Fig. 3 shows a typical TGDTA curve of the silica powder modified by ml of HTMS after ball milling for 24 h. The DTA curve showed two peaks at approximately 130 and 300 °C. The first endothermic peak corresponds to the loss of physically adsorbed and/or hydrogenbonded water from the silica powder [22].The second exothermic peak is ascribed to the thermal decomposition of hexyl groups [11].
