Preparation of monodisperse ZrO2 ceramic microspheres (>200 μm) by co-axial capillary microfluidic device assisted internal gelation process
The internal gelation process was combined with a co-axial capillary microfluidic device to prepare monodisperse ZrO 2 ceramic microspheres . Large sized gel microspheres in the range of hundreds of micrometers could be produced with the capillary microfluidic device with co-axial flow structure and the large sized outlet tubing. After drying and sintering, large sized ZrO 2 ceramic microspheres (>200 μm) which had good sphericity and narrow size distribution were prepared.
