I am facing problems with preparing a colloidal dispersion of ZrO2 nanopowder.
Tried sonicating it for about 10 mins still no success.
Would appreciate some info related to this!!
Thanks
Try to add some surfactants to avoid aggregating nanopartcles.
Check the zeta potential and use ammonium salt of polyacrylic acid
It is a very good dispersing agnet
Sonication using the help of micronsized zirconia beads and subsequent fractionation could be of significant benefit for deaggregation, in some cases.
You should synthesize or buy stabilized nanoparticles in fluid dispersion. Otherwise particles get strongly aggregated due to interparticle bonds.
