Abstract: Description of gel-to-crystallite conversion process is made towards the synthesis of nanocrystalline titanates and aluminates. Thermodynamic and kinetic factors governing the conversion of a gel to meta-stable and stable nanocrystalline products(s) are discussed. Correlations between these factors and the preparative conditions employed for the syntheses of titanates and aluminates are arrived at.

 

Keywords: chemical synthesis; ceramics; oxides; meta-stable intermediates; stable intermediates; gel-to-crystallite conversion; nanocrystalline titanates; nanocrystalline aluminates; thermodynamics; kinetics; nanotechnology.
