Nano-aluminum-pho sphate via a polymerized organic-inorganic complex route

Nano-aluminum-phosphate (AlPO4) powder has been synthesized by an ethylene glycol (EG), polymerization, complexation route. The AlPO4 powder has a particle size <= 10 nm via TEM. The differential thermal analysis (DTA) and the thermo-gravimetric analysis (TGA) show complete burn-out of organics is achieved <= 680 degrees C and crystallization initiates <= 500 degrees C. X-ray diffraction (XRD) shows crystallization is well developed by 700 degrees C. Scanning electron microscopy shows a fine grain size with fused edges indicating partial sintering of the powder at 900 degrees C. (c) 2007 Elsevier B.V. All rights reserved.
