THEORY AND TECHNOLOGY OF SINTERING, THERMAL AND CHEMICOTHERMAL TREATMENT--PRESSING AND SINTERING OF NANOSIZED HYDROXYAPATITE POWDERS

摘要

The paper examines the compactability and sintering of nanosized synthetic hydroxyapatite (HA) powders for increasing the durability and strength of HA ceramics. The granulation of HA powders and limitation of the applied pressure prevent delamination in pressing. Porous HA samples show homogeneous nanoporous structure, high compactability, and excellent sinterability, which is better than that of nanosized powders.
