The zirconia surface is rough due to grinding beneath the glaze layer. As it can be seen, the glaze layer is quite thin, having a maximum of 10μm thickness. Surface polishing can significantly reduce roughness and a polished surface can retain its low roughness even after the glaze layer has been removed.
Zirconia Machining and Grinding. While the same design features common to alumina ceramics; blind holes, threads etc. are easily produced in Zirconia the grinding time required is about fifty percent more. The post-grinding surface finish is significantly better than a comparable feature in most aluminas. Zirconia is much more dense, finer ...
