Description:
<jats:p>Highly porous biomaterials with a structure close to that of cancellous bone
have been prepared using biogenic hydroxyapatite and glass of the
SiO2-Na2O-CaO system by a replication of the polymer template structure. It
has been established that during sintering of the samples the hydroxyapatite
decomposes, which involves the formation of glass-ceramics containing phases
of renanit NaCaPO4, calcium phosphate silicate Ca5(PO4)2SiO4, calcium
pyrophosphate Ca2P2O7 and impurities of hydroxyapatite Ca5(PO4)3(OH).
Structural characteristics and mechanical properties of the obtained
materials are promising for the replacement of defective cancellous bone.</jats:p>
