Alumina foam was prepared by the direct foaming method. The foam was stabilized by in situ partially hydrophobized particles of Al2O3. Dodecylbenzenesulphonic acid was used for hydrophobization and it also acted as a foaming agent. The composition of

Hydroxyapatite was synthesized by reacting Ca(HCO3)2 with (NH)2HPO4 at 25°C. It was demonstrated that, for the crystallization of hydroxyapatite on a substrate as a coating, it is important to suppress the homogeneous nucleation in the bulk volume o
