Effect of several calcination temperature on different concentration zinc substituted calcium phosphate ceramics
Zinc substituted calcium phosphate ceramics powders were produced from precipitation method using calcium nitrate, zinc nitrate and ammonium dihydrogen phosphate solutions. Several zinc ions concentrations (5, 10, and 15 mole %) were substituted into calcium phosphate ceramics with the (Ca+Zn)/P ini...

Zinc substituted calcium phosphate ceramics powders were produced from precipitation method using calcium nitrate, zinc nitrate and ammonium dihydrogen phosphate solutions. Several zinc ions concentrations (5, 10, and 15 mole %) were substituted into calcium phosphate ceramics with the (Ca+Zn)/P initial ratio were set to 1.67. Calcium phosphate powders were then calcined at 600, 700, 800, 900, and 1000°C to observe its effect on the material phase behavior. By increasing the calcination temperature, XRD peaks changed from broad to narrower shape indicating that the powders are highly crystalline. Hydroxyapatite (HA) partly transformed to another phase which is tricalcium phosphate (β-TCP) at 700°C confirming the formation of biphasic calcium phosphate ceramics. FESEM observations clearly exhibit that the particles are in nanosized scale which explains why as zinc concentration increases, the particles tend to be agglomerated. © 2015 Penerbit UTM Press.
