| description |
Calcium phosphate cement (CPC) has been synthesized via a straightforward hydrothermal route. Calcium
oxide and ammonium dihydrogen phosphate were used as calcium and phosphate precursors. The precursors were
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 powder and distilled water at the powder-to-liquid (P/L) ratio of 1.5. Poly(vinyl
alcohol) (PVA) of 1 to 7% (w/w) was added and its effect on physical properties was investigated. It was proved that
PVA addition up to 7% (w/w) has shortened the setting time but decreased the injectability. The PVA free CPC has
the initial and final setting times of 71 and 187 min, respectively and the injectability of 99.92%. The compressive
strength also increased with the amount of PVA added in CPC. In addition, soaking CPC in Ringer's solution for 7,
14 and 21 days also gave remarkable effects on cohesion, microstructure and mechanical properties of the cement. |
