Nano-aluminum-phosphate 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 ≤10nm via TEM. The differential thermal analysis (DTA) and the thermo-gravimetric analysis (TGA) show complete burn-out of organics is achieved ≤680°C and crystallization initiates ≤500°C. X-ray diffraction (XRD) shows crystallization is well developed by 700°C. Scanning electron microscopy shows a fine grain size with fused edges indicating partial sintering of the powder at 900°C.
