The 0.7Pb(Mg1/3Nb2/3)O3-0.3PbTiO3 ceramic films were prepared using the water-based tape casting method. Two main components of slurry are water and solids. concentrations other chemicals, surfactant binder, at level 1 wt.%. Both binder eco-friendly polymers. Additional chemicals not required. optimal concentration determined through viscosity measurements. density ceramics was studied as a fun...

Both monolithic and multilayer mullite-alumina ceramic composites dedicated to ballistic applications were produced by uni-axial pressing tape casting before being sintered at 1510 °C. The compositions combining andalusite kaolin in addition α-alumina exhibit the more promising mechanical properties, reaching performances of pure alumina. However, for a given bulk density value, significant imp...

Abstract In the era of miniaturization and hybridization, quest for novel materials multilayer packaging had been increased. The includes High Temperature Co-Fired Ceramics (HTCC), LTCC ULTCC. which is mixture ceramic glass (which reduces firing temperature ceramics) has attracted many researchers due to its lower temperature(<900°C). Due this sintering temperature, it can be cofired with lo...

A complete cell consisting of NiO-Ce0.8Sm0.2O3−δ//Ce0.8Sm0.2O3−δ//(La0.6Sr0.4)0.95Co0.2Fe0.8O3−δ elaborated by a co-tape casting and co-sintering process tested in operating fuel conditions exhibited strong degradation performance over time. Study the cathode–electrolyte interface after testing showed, on one hand, diffusion lanthanum from (La0.6Sr0.4)0.95Co0.2Fe0.8O3−δ into Sm-doped ceria lead...

Al2O3/glass/hBN composites were successfully fabricated for the LTCC applications. Alignment and homogeneous distribution of platelet hBN particles during tape casting allowed high (5 wt%) loading as well facilitated densification at 800°C (density 2.65 g/cm3, apparent porosity 0.7%). XRD results proved that neither chemically reacted with other phases nor decomposed temperature, which was crit...

introduction: the aim of this study was to evaluate the effect of bridge orientation in casting machine on castability and quality of base metal castings. methods: three groups of patterns with different direction and lengths in casting machine were casted and then studied qualitatively and quantitatively using mean and standard deviation in table of frequency. results: larger nodules and poros...
