Influence of anionic stabilization of alumina particles in 2-propanol medium on the electrophoretic deposition and mechanical properties of deposits

Popis výsledku v původním jazyce

The ceramic dispersions were prepared using 0.85, 1.70, 4.25, 12.75 or 21.25 wt.% of monochloroacetic, dichloroacetic or trichoroacetic acid,15 wt.% alumina and 2-propanol. The mechanism of anionic stabilization in 2-propanolic media was described. Alumina green bodies were preparedfrom the stable dispersion via electrophoretic deposition (EPD). It was found that increasing dispersion conductivity significantly influenced theEPD yields. The most effective electrophoretic depositions were performed fromdispersions with conductivity in range 4.0?5.3 104S m1.Deposits with the highest green density were prepared from the dispersion stabilized by trichloroacetic acid. This behavior was explained by lowvoltage drop during deposition. The surface roughness was high at low dispersion conductivity and with increasing acid concentration in dispersionthe surface of deposits was smoother. The mechanism of particle arrangement in deposit was discussed. Influence of stabilizer amount in thedispersi
