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 ≤10 nm 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.
