Paper Title:
Development of High-Speed Centrifugal Compaction Process of Alumina
  Abstract

High-Speed Centrifugal Compaction Process (HCP) is one of slip-using compacting method in which the compacts are obtained as sediments under huge centrifugal force. Compacting mechanism of the HCP differs from other slip using compacting methods. The unique compacting mechanism of the HCP leads a number of characteristics such as a higher compacting speed, wide applicability for net shape formation, etc. Moreover, the most outstanding characteristics of the HCP can be found in homogeneous and flawless microstructure of the green compacts, because the process possesses an intrinsic defect removing function. That is, the defect inducing matters in slips (powder aggregates, inclusions, bubbles) are removed from the main part of the compact by the classification effect of centrifuge, and therefore the HCP alumina exhibits superior sinterabiliy and higher strength and hardness than most other aluminas. Many of the advantageous characteristics of the HCP can be improved with a higher centrifugal force.
