提出了一种新的粉末材料压制方法。高速离心压实工艺(HCP)利用约10000克离心力进行压实。HCP适用于超细、亚微米、纳米级粉末的净形压制。HCP具有不同于包括压力铸造(PC)在内的其他胶体工艺的独特的压制机理，并具有许多有用的特性。与PC相比，HCP具有更高的压实速度，对网状成形的广泛适用性，以及缺陷消除功能。HCP氧化铝具有均匀、无瑕疵的绿色显微结构，具有优异的烧结性和较高的强度和硬度。
A new compacting method for powder materials is presented. High-Speed Centrifugal Compaction Process (HCP) utilizes centrifugal force of about 10,000 g for the compaction. HCP is suitable for net shape compaction of fine sub-micron and nano-powders. HCP possesses a unique compacting mechanism that is different from other colloidal processes including Pressure Casting (PC), and has a number of useful characteristics. HCP has a higher compacting speed than PC, wide applicability for net shape formation, as well as a defect removing function. Because of homogeneous and flawless green microstructure, HCP alumina shows superior sinterability and higher strength and hardness than most of other aluminas.
