- W1998534912 abstract "Abstract The preparation and characteristics of zirconium-modified alumina-aluminum phosphate were examined to determine their suitability as controlled-pore, catalytic supports. The composites were prepared by coprecipitation, at constant pH, of the metal ions using a mixture of ammonium phosphate and ammonium hydroxide as precipitating agents. Surface area and porosity were dependent upon the exact preparation parameters and were variable over a wide range. As the Al/Zr ratio increased, the materials exhibited the characteristic large surface area and porosity of alumina-aluminum phosphate. The surface properties also displayed a strong dependence upon the pH of precipitation with a higher pH resulting in a more rigid and, hence, less porous composite. Examination of the thermal stability of the supports by DTA and powder X-ray diffraction showed increased stability of the mixed phases over the pure components, with crystallization occurring only after 1000°C annealing. The resulting X-ray pattern obtained after high temperature annealing was related to the initial porosity of the materials." @default.
