Lead-zirconate-titanate (PZT) ceramics with zirconate-titanate (65:35) have been synthesised with the substitution of lanthanum (6, 7 and 8 mol %). Samples were prepared by solid-state reaction route.The x-ray diffraction study shows the formation of a si... see more

The shortcomings at elevated operation temperatures of the standard material yttria-stabilized zirconia (YSZ) for thermal barrier coatings (TBCs) have initiated many research activities seeking alternatives. One candidate is the pyrochlore lanthanum zirco... see more

State-of-the-art technology has been developed for the fabrication of 33 mm hollow cylindrical elements from Lanthanum-dooed lead zirconate titanate-based material suitable for oassive surveillance arrays of SONAR systems. It covers properties of the mate... see more

The creation of new non-toxic materials that combines high osteointegration and strength characteristics is an urgent contemporary challenge. The use of complex oxides, such as lanthanum zirconate (La2Zr2O7), as non-reservable alloplastic implant material... see more

Present work is on synthesis of high purity Nano-structured TBC materials, Lanthanum Zirconate and YSZ. They were prepared via wet chemical routes, starting from the indigenous source minerals such as zircon and monazite available in the beach sand. This ... see more

Elastic properties of lanthanum-modified lead zirconate-titanate (PLZT) relaxor ceramic oxide used as optical shutters are required for device design, storage and field purposes. Therefore, acoustic phonon mode velocity and related elastic constant of PLZ... see more

Lanthanum modified lead zirconate titanate antiferroelectric ceramics has been studied by using X-ray diffraction, dielectric analysis and ferroelectric hysteresis loops. Both antiferroelectric-orthorhombic (Pbam) and ferroelectric-rhombohedral (R3c) phas... see more

Lanthanum doped lead zirconate titanate (Pb1-xLax)(ZryTi1-y)O3 (PLZT x/y/1-y) relaxor ferroelectric ceramics show no macroscopic polarization down to low temperatures as shown by the present dielectric and Raman scattering measurements on PLZT-10/65/35. T... see more

The lead zirconate titanate (PZT)-graphite piezocomposites have potential for higherpiezoelectric sensitivity, lower acoustic impedance, higher piezoelectric voltage constants, higherelectromechanical coupling coefficient, and higher hydrostatic coefficie... see more
