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...
متن کاملPreparation of aliened porous Ni-GDC nano composite by freeze-casting process
This current study reports preparation of Nickel-Gadolinium doped Ceria (Ni-GDC) composite via controlled unidirectional freeze casting of aqueous-based GDC slurry completed with nickel infiltrated into the porous GDC samples. Gadolinium doped ceria powder prepared by gel-combustion synthesis method. The oxide powder was confirmed to be the fluorite-structured of Ce0.8Gd0.2O1.9 solid solution b...
متن کاملRECYCLING PRACTICES OF SPENT MgO-C REFRACTORIES
The recycling options of spent MgO-C refractories from an electrical arc furnace (EAF) have been evaluated. The economic, quality of spent refractories and products made from it, the ease of implementation of a recycling practice and the interest of steel melt shops were considered. It was decided that the best option of most EAF shops would be to recycle spent MgO-C refractory as a foaming sla...
متن کاملPreparation of Cu36Zr48Ag8Al8 Bulk Metallic Glass with a Diameter of 25mm by Copper Mold Casting
The Cu36Zr48Ag8Al8 alloy exhibits very high glass-forming ability. We have succeeded in synthesizing a Cu36Zr48Ag8Al8 bulk glassy alloy with a diameter of 25mm using the conventional copper mold injection casting. The absence of a crystalline phase was confirmed by X-ray diffraction and differential scanning calorimetry examinations. The critical cooling rate for formation of a glassy phase for...
متن کاملThe effect of slip casting parameters on the ultrafine microstructure and density of pore-free YAG ceramic obtained by vacuum sintering
In this study, the effect of slip casting parameters on the ultrafine microstructure and the density of pore-free YAG ceramic was evaluated. A stable, high concentrated aqueous YAG slurry using Dolapix-CE64 as a dispersant was prepared. The effect of dispersant concentration as well as the solid load on the stability and rheological behavior of the slurry was also studied. The optimal dispersan...
