Thermal analysis of SYNROC gel microspheres [electronic resource]
Thermoanalytical methods were used to characterize SYNROC microspheres at three stages of the internal gelation process: unwashed spheres, washed spheres, and washed-and-dried spheres. Linear-programmed heating experiments were performed using thermogravimetric analysis, differential scanning calori...

| 520 | 3 | |a Thermoanalytical methods were used to characterize SYNROC microspheres at three stages of the internal gelation process: unwashed spheres, washed spheres, and washed-and-dried spheres. Linear-programmed heating experiments were performed using thermogravimetric analysis, differential scanning calorimetry, differential thermal analysis, and mass spectrometry for producing the thermograms. The data were used to elucidate thermal reactions occurring between ambient and 800/sup 0/C. The principal reactions were the release of waters from various sources, the decomposition and combustion of gelation additives (hexamethylenetetramine and urea), and the decomposition of carbonates. Data also demonstrated the efficiency of the washing process. Kinetic studies were carried out by differential scanning calorimetry and differential thermal analysis to determine activation energies for certain pyrolysis reactions. 8 figures. | |
