Porous alumina from protein foaming-consolidation method containing hydrothermal derived hydroxyapatited powder

Porous alumina containing hydrothermal derived hydroxyapatite (HA) composite were successfully fabricated via protein foaming-consolidation method. Alumina and HA powders were mixed with yolk, starch and darvan 821 A at an adjusted mass ratio to make slurry. The slurries were cast into cylindrical s...
