Abstract
The present work reports a simple process for fabrication of porous tricalcium
phosphate (TCP) ceramics from aqueous powder slurries using wheat particles as
pore forming agent. The objective of this research is to learn the effect of stirring
time and sintering temperature on the physical properties of porous TCP. Wheat
particles incorporated in aqueous TCP slurries and stirred for 1, 2 and 3 hours.
Subsequently the slurry was dried in oven at 80˚C for 24 hours and 120˚C for 8
hours. The dried green bodies showed shrinkage in the range 53 -56%. Removal
of the pore former followed by sintering at 1000 and 1100˚C produced TCP
bodies with porosity 59 – 78% and compressive strength 0.3 - 2.5 MPa.
