FABRIKASI TRI KALSIUM FOSFAT MENGGUNAKAN WHEAT PARTICLES SEBAGAI AGEN PEMBENTUK PORI

Abstract

The present work reports a simple process for fabrication of tricalcium phosphate (TCP) ceramics from aqueous powder slurries using wheat particles as pore forming agent. Wheat particles incorporated in aqueous TCP slurries rapidly absorb water on heating and transform it into a strong gel. The dried green bodies showed shrinkage in the range 53,22-55,87%. Removal of the pore former followed by sintering at 1000 and 1100˚C produced TCP bodies with porosity 59,48–78,40% and compressive strength 0,30-2,53 MPa.
