چکیده مقاله:

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 1250 °C led tothe formation of a dense microstructure as was evidenced by the scanning electron microscopy.

Preparation of hexaferrite multilayers by tape casting

Tape casting technics were used to realize a screen with continuous change in characteristics. Different hexaferrite compositions owned by the Ba3C02-~Zn~Fe24041 (Z) family were synthetized by coprecipitation method and calcined at 1200 "C in air. Then a slurry containing this powder is slip casted using tape casting. The tapes are dried under magnetic fied in order to orient the magnetic plate...

Freeze casting of hydroxyapatite scaffolds for bone tissue engineering.

Although extensive efforts have been put into the development of porous scaffolds for bone regeneration, with encouraging results, all porous materials have a common limitation: the inherent lack of strength associated with porosity. Hence, the development of porous hydroxyapatite scaffolds has been hindered to non-load bearing applications. We report here how freeze casting can be applied to s...

Ethanol-based Tape Casting Process of the Textured Bi0.5(Na0.80K0.20)0.5TiO3-BiFeO3 Ceramics

The rheological and tape casting behavior of ethanol-based Bi0.5(Na0.80K0.20)0.5TiO3-7 mol% BiFeO3 (BNKT-BF) slurries was investigated. The effect of sintering temperature profile on texture development with a preferred orientation was also studied. A 50 MPa pressure assisted three step sintering profile promoted extensive texture development together with densification. The role of BF as a sin...
