| description |
The objective of this study is to determine the effects of excess calcium on the
handling and mechanical properties of hydrothermal derived calcium phosphate cement (CPC)
for bone filling applications. Hydroxyapatite powder was synthesized via hydrothermal method
using calcium oxide, CaO and ammonium dihydrogen phosphate, NH4H2PO4 as the calcium
and phosphorus precursors respectively. The effects of calcium excess were evaluated by
varying the CaO content at 0, 5 and 15 mole %. The precursors were then refluxed in distilled
water at 90-100˚C and dried overnight until the calcium phosphate powder was formed. CPC
was then produced by mixing the synthesized powder with distilled water at the powder-toliquid
(P/L) ratio of 1.5. The result from the morphological properties of CPC shows the
increase in agglomeration and particles size with 5 mole % of calcium excess but decreased
with 15 mole % of calcium excess in CPC. This result was in agreement with the compressive
strength result where the CPC increased its strength with 5 mole % of calcium excess but
reduced with 15 mole % of calcium excess. The excess in calcium precursor also significantly
improved the setting time but reduced the injectability of CPC. |
