Effect Of pH Condition During Hydrothermal Synthesis On The Properties Of Hydroxyapatite From Eggshell Waste

Hydroxyapatite (HA) powders were synthesized using eggshell waste through hydrothermal method to develop bioceramics materials for medical applications. The effects of the pH conditions during the synthesis on the phase behaviour, crystallite size, crystallinity and morphology of as-synthesized cer...
