Abstract
High-Speed Centrifugal Compaction Process (HCP) is a variety of wet compacting method for fine ceramic powders by using huge centrifugal force of about 10,000g. The compacting mechanism of the HCP differs from that of slip casting, a conventional wet compaction method, and therefore the HCP possesses a number of unique characteristics such as a higher compacting speed than pressure casting, wide applicability for net shape formation, as well as defect removing function. Because of homogeneous and flawless green microstructure, the HCP alumina shows a superior sinterabiliy and higher strength and hardness than most other alumina. These advantages can be emphasized with a higher centrifugal force.
