PROCESSING OF CONCENTRATED AQUEOUS ZIRCONIA-BIOGLASS SLIPS BY SLIP CASTING

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 differen...

Investigation of the mechanical properties of various yttria stabilized zirconia based thin films prepared by aqueous tape casting

In this study various yttria doped  zirconia based thin films were prepared by the aqueous tape casting method. The rheological property of the paste was studies. The phase content and microstructure of the samples was investigated by X-ray diffraction and scanning electron microscope, respectively. The mechanical properties of thin films were studied by Vickers microhardness and nanoindentatio...

Multicomponent Concentrated Aqueous Electrolyte Solutions

Semisolid Processing of Al/β-SiC Composites by Mechanical Stirring Casting and High Pressure Die Casting

Component dynamics in polyvinylpyrrolidone concentrated aqueous solutions.

(2)H-nuclear magnetic resonance (NMR) and neutron scattering (NS) on isotopically labelled samples have been combined to investigate the structure and dynamics of polyvinylpyrrolidone (PVP) aqueous solutions (4 water molecules/monomeric unit). Neutron diffraction evidences the nanosegregation of polymer main-chains and water molecules leading to the presence of water clusters. NMR reveals the s...
