Alumina ceramic finishing and packaging process

Some alumina ceramic materials need to be finished after sintering. For example, articles that can be used as artificial bones require a high surface finish, such as a mirror surface, to increase lubricity. Due to the high hardness of the alumina ceramic material, it needs to be finished with a harder abrasive polishing brick material. Such as SIC, B4C or diamond drill. Grinding is carried out step by step from coarse to fine abrasive, and the final surface is polished. Grinding and polishing can generally be carried out using Al2 micropowder or diamond powder of <1 μm micron. In addition, laser processing and ultrasonic processing methods of polishing and polishing can also be used.
