| Abstract: | Aluminum polyphosphate was prepared from aluminum nitrate solution and sodium polyphosphate solution with cation exchange resin in the molar ratio of Al/P = 1/3. Urea and hexamethylenetetramine were added in this preparation process. The thermal behavior of the obtained phosphates was analyzed by differential thermal analyses, X-ray diffraction, and Fourier transform infrared spectroscopy. Furthermore, these materials and their thermal products were estimated by specific surface area, pore size distribution, particle size distribution, acid strength, amount of acidic sites, and adsorption of trimethylamine. |
