Effects of powder preparation and sintering procedure on microstructure and dielectric properties of PLZT ceramics

In the temperature range 600-750 K, the electrical resistivity decreases abruptly (Fig. These changes are due to the amorphous phase crystallization of the nickel powder.

also observed for eutectic additives (Fig. Di ff raction pattern of Ca 0.5 Sr 0.5 TiO 3 prepared with di ff erent amount of eutectic composition.. Dielectric properties of Ca 0.5 Sr

perature of PZTN ceramics is lower for about 5 °C and relative permittivity is higher in comparison to the pure PZT samples. Thus, room temperature relative permit- tivity of PZTN

Compared with as-cast AZ80 alloy, yield strength of the alloys with solid solution treatment remarkably decreased, while the tensile strength and ductility increased

Investigation on the microstructure and properties of HSS reveals that inoculation of HSS by ferrovanadium can break up the coarse continuous carbide network,

It is established that all investigated samples are dielectric materials with conductivity between 10 -9 and 10 -13 (Ω·cm) -1 at room temperature, dielectric permittivity from

Besides the increase of sliding friction coefficients, the wear rates of the boronized specimens were much lower compared with those of the as-sintered specimen under the

Tamarind powder shows the higher green and shear strength due to the finer in nature of powder.Permeability number decreases with the increases the additives contents .The
