| 제목 | Control of ceramic beads size by emulsification method of zirconia slurry using Taylor reactor |
| 초록 | As the importance of nano process technology such as materials for energy storage, materials for flexible devices, and materials for harmful substances increases, demand for micro-ceramic balls is increasing. High sphericity and uniformity are required for high crushing power and long lifetime of micro-ceramic beads. In this study, ceramic beads were prepared by gel casting method using slurry prepared by mixing partially stabilized zirconia, dispersant, monomer, and cross - linking agent and then adding initiator. The slurry and oil phase were emulsified using a Taylor reactor for mechanical agitation. The size of the emulsion droplet was controlled by the variation of the flow parameter due to the variation of the Taylor number (Ta) and the Reynolds number (Re). As the rotational speed of the inner cylinder increased, the smaller the size of the fine beads was, the higher the Ta value was. When the distance between the inner wall and the outer’s of the Taylor reactor was 1 mm and 2.75 mm, the size of the prepared micro beads ranged from 5 to 50 μm and from to 20 to 100 μm, respectively. |
