Influence of composition and isothermal sintering on the properties of hydroxyapatite bioceramic bodies

This work reports the influence of chemical composition and sintering schedule on the properties of sintered bodies of hydroxyapatite (HA) bioceramic. The method of preparing sintered bodies by solid state reaction and uniaxial pressing. The raw material used calcium carbonate (CaCO 3 ) and ammonium...
