Alumina-composite botanical abrasives were prepared by using aliphatic acid, wax, etc. to make a walunt shell composite with alumina powder. A barrel polishing apparatus was used to perform polishing experiments on various composite ceramics of the Al<sub>2</sub>O<sub>3</sub>-Y<sub>2</sub>O<sub>3</sub>-ZrO<sub>2</sub>-MgO family (Family I, with high hardness and tenacity) and the Al<sub>2</sub>O<sub>3</sub>-Y<sub>2</sub>O<sub>3</sub>-MgO family (Family II, with high porosity). The alumina-composite botanical abrasives were found (1) to be capable of gradually increasing the polished amount with polishing time for all ceramics, with resulting improvement of surface roughness, (2) to be effective for smoothing surfaces of Family I composite ceramics, though with low processing efficiency, and (3) to exhibit high polishing speeds for Family II composite ceramics, though with high roughness of the finished surface.
