Paper Title:
Fabrication of Calcium Based Fine Ceramic Materials by Recycling Eggshell
  Abstract

A raw eggshell shows CaCO3 phase, and pure CaO can be obtained by calcination of the raw eggshell. And the morphology of the calcined eggshell is grape-type granular with uniform particles. By using the recycled eggshell, biocompatible and highly sinterable calcium phosphate bio-ceramics were successfully fabricated, such as hydroxyapatite (HAp) and b-tricalcium phosphate (b-TCP), and wollastonite (CaSiO3). The observed phases and microstructures on the powder synthesis process are dependent on the content of eggshell and calcination temperature. In this study, the crystalline development and the microstructure of synthesized powders and the densified specimens are examined by X-ray diffractometry and scanning electron microscopy.
