Abstract

Silica hollow microspheres containing phosphorous have been prepared by a sol-gel/emulsion method which uses tetraethoxysilane (TEOS) as the precursor for the SiO2 and phosphoric acid (H3PO4) as the precursor for P2O5. The hollow structure forms an emulsion system which is composed of an oil phase (kerosene, sorbitan monooleate (Span 80)) and an aqueous phase (a viscous sol solution of ethanol, TEOS and H3PO4). Some of the phosphorous remains in the final silica shell structure even after calcination at 650°C. The hollow structure of the P2O5-SiO2 (silicophosphate) was characterized by X-ray diffraction (XRD), polarized optical microscopy (POM), scanning electron microscopy (SEM), nitrogen adsorption measurement and Fourier transform infrared spectroscopy (FTIR).

Key words： P2O5-SiO2; hollow microspheres; sol-gel/emulsion; phosphoric acid
