Fabrication Of Porous Β-Tricalcium Phosphate Granules Cements By Using Β-Tricalcium Phosphate Granules As Starting Materials
The purpose of this study is to fabricate porous β-tricalcium phosphate granular cement using different size of β-tricalcium phosphate granules (300-600 μm and 600-1000 μm). To achieve this objective, β-tricalcium phosphate granules were exposed to 1.0 mol/L of phosphoric acid solution with liquid t...

| description | The purpose of this study is to fabricate porous β-tricalcium phosphate granular cement using different size of β-tricalcium phosphate granules (300-600 μm and 600-1000 μm). To achieve this objective, β-tricalcium phosphate granules were exposed to 1.0 mol/L of phosphoric acid solution with liquid to granular ratio (L/G) of 1:1. Besides, the setting time used in this study were fixed at 1, 3, 5, 7, and 24 hours. The set specimen were characterized by XRD to detect the formation of dicalcium phosphate dihydrate (DCPD) phase in the set specimen. It was found that when smaller size of β-tricalcium phosphate granules were used, more DCPD formation were observed. This consistent within the XRD result which the peak area ratio of DCPD for small granules size is higher than the bigger granules. SEM results demonstrated that more DCPD crystals were interlocked each other in the case of small size of β-tricalcium phosphate granule. The higher amount of interlocked DCPD crystal will increased the compression strength of set specimens. In contrast, the percentage of porosity decrease with increasing the formation of DCPD crystal. With 24 hours of setting time using 300-600 μm of granules the porosity percentage were 42.15 % while with size of 600-1000 μm it shows 48.76 % of porosity. With lowest percentage of porosity the mechanical strength shows highest compressive strength which is 1.16 MPa compared to higher porosity which shows only 1.00 Mpa. Therefore, it shows that the smaller size of β-tricalcium phosphate granules is appropriate to fabricate porous β-tricalcium phosphate granular cements. |
