The effect of organic vehicle on the injection molding of ultra-fine zirconia powders

The compatibilities between the different binder ingredients were investigated by calculating the discrepancy of their compatibility parameters. The effects of different plasticizers involving dibutyle phthalate (DBP), organic alcohol glyceryl (OAG), caster oil (CO) and surfactants involving steric acid (SA), oleinic acid (OA) and Tween 80 (T80) on the behavior of zirconia suspensions were compared. The influence of the contents of dibutyle phthalate on the flow behavior of the feedstocks and the properties of the sintered parts were also examined.
