Experimental Studies and Condition Monitoring of Auxiliary Processes in the Production of Al2O3 by Sol–Gel Technology

Powders and granules of heavy metal oxides produced through condition monitoring are in high demand as intermediate products for obtaining fine-grained ceramics a wide range applications, i.e., nuclear fuel elements power plants. Sol–gel technology to produce (UO2), well catalysts (ThO2) organic synthesis the form from pressed microspheres, is promising method obtain powders (fine-graded ceramics). Al2O3 was selected model analog at stages solution sol, formation gelation droplets, preparation gel spheres their further washing drying, recovery firing particles. In study, main parameters were substantiated, e.g., diameter angle inclination axis holes perforated shell, multiplicity sol circulation before holes, coefficients liquid (sol) flow rate, oscillation frequency disperser, concentration surfactant acid sol. All these affect characteristics that obtained by sol–gel technology. Moreover, recommendations increase productivity energy efficiency production also given. particular, it found 70–80 Hz leads granulometric composition 2.0–2.2 mm. A hole 0.85 mm 100 slightly change this 1.2–2.0 mm, while maintaining monodispersity.
