高速离心压实工艺（HCP）是利用10000克左右的巨大离心力对陶瓷细粉进行湿式压实的多种方法。HCP的压实机理不同于传统湿法浇铸的压实机理，因此HCP具有许多独特的特点，如压实速度比压力浇铸快，对净形地层的适用性广，以及缺陷消除功能。HCP氧化铝具有均匀、完美的绿色组织，具有较好的烧结性能和较高的强度、硬度。这些优点可以通过更高的离心力来强调。
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.
