Abstract


Tricalcium Phospate (TCP) scaffold has been made successfully using protein foaming-starch consolidation method. The objective of this research is to investigate the influence of addition of  dispersant and starch on physical, chemical and mechanical properties of TCP scaffold. The slurry was begun with mixing the TCP powder, starch with Darvan 821A and yolk. Subsequently the slurry was mechanically stirred in rate of 150 rpm for 3 hours. The slurry was poured in open cylindrical mold and dried in air oven at 180°C for 1 hour. The green bodies were released from the mold and burnt at 600°C ended by sintering at 1100°C for 1 hour. TCP scaffold with porosity of 73.7-79.30% and compressive strength of 1.88-2.4 MPa were obtained. The pore size of the TCP scaffold is 166.7-318.18µm, indicating applicability for bone implant application.
