TAPE CASTING OF NON-AQUEOUS HYDROXYAPATITE SLIPS

Thin sheets of hydroxyapatite were fabricated by tape casting process. The non-aqueoustape casting formulation was optimized by adjusting the concentration of organic additivesspecially those of binder and plasticizer in the slurry. The optimized slurry was cast on a glasscarrier using a designed laboratory scale doctor blade. Following a binder removal stage, thetapes were sintered at different temperatures in air atmosphere. Heat treatment at ۱۲۵۰ °C led tothe formation of a dense microstructure as was evidenced by the scanning electron microscopy.
