Effect of hydroxyapatite and tricalcium phosphate addition on protein foaming-consolidation porous alumina
Porous alumina-hydroxyapatite (HA) and alumina- tricalcium phosphate (TCP) composites have been fabricated to investigate the effect of HA and b-TCP addition on protein foaming-consolidation derived porous alumina. HA and b-TCP loadings along with yolk content, starch content, and sintering tem...

| description |
Porous alumina-hydroxyapatite (HA) and alumina-
tricalcium phosphate (TCP) composites have been
fabricated to investigate the effect of HA and b-TCP
addition on protein foaming-consolidation derived porous
alumina. HA and b-TCP loadings along with yolk content,
starch content, and sintering temperature were varied to
modulate performance of the porous composites. The
rheological behavior of slurry shifted from pseudoplastic
flow to a Newtonian fluid with increasing yolk concentration.
The foaming capacity of slurry increased with yolk
addition. The addition of starch into slurry resulted in
bigger pore size and avoided the porous bodies from
cracks. The shrinkage of sintered bodies increased with
increasing HA loading, but decreased with increasing
b-TCP loading. The compressive strength of porous alumina-
HA body was found 2.9 MPa at 45.8% porosity and
20.4 MPa at 36.8% porosity. The increasing porosity of
porous alumina-TCP body from 56.1 to 61.6% improved
the compressive strength from 3.1 to 4.2 MPa. Increasing
sintering temperature resulted in large grain size among
powder particles, thus improving the compressive strength
of porous bodies. Preliminary results of DF-1 cells culture
on the surface of porous alumina and alumina-TCP samples
are also reported. |
