Enhanced Performance of La0.6Sr0.4Co0.2Fe0.8O3-\delta(LSCF) Cathodes with Graded Microstructure Fabricated by Tape Casting

Enhanced Performance of La0.6Sr0.4Co0.2Fe0.8O3−δδ (LSCF) Cathodes with Graded Microstructure Fabricated by Tape Casting

La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF) powders with different particle sizes, synthesized through a citrate complexation method and a gel-casting technique, are used to fabricate porous LSCF cathodes with graded microstructures via tape casting. To create porous electrodes with desired porosity and pore structures, graphite and starch are used as pore former for different layers of the graded cathode....

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...

Investigation of Graded La2NiO4+ Cathodes to Improve SOFC Electrochemical Performance

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...

Ceramic planar waveguide laser of non-aqueous tape casting fabricated YAG/Yb:YAG/YAG

Ceramic YAG/Yb:YAG/YAG planar waveguide lasers were realized on continuous-wave and mode-locked operations. The straight waveguide, fabricated by non-aqueous tape casting and solid state reactive sintering, enabled highly efficient diode-pumped waveguide continuous-wave laser with the slope efficiency of 66% and average output power of more than 3 W. The influence of the waveguide structure on ...
