Volume 6, Issue 6 , June 2015, , Pages 531-537


   The present paper highlights the optical properties change in thermally evaporated As40Sb15Se45 amorphous film of 800 nm thickness with laser irradiation. The as-prepared and illuminated films were studied by X-ray diffraction, Energy dispersive X-ray analysis. The optical properties were calculated ...  Read More

Observation Of Dielectric Relaxor Behavior In Pb0.95Sr0.05(Zr0.5Ti0.5)O3 Ceramics

Nawnit Kumar; Patri Tirupathi; Bineet Kumar; Mukul Pastor; A. C. Pandey; R. N. P. Choudhary

Volume 6, Issue 4 , April 2015, , Pages 284-289


  We reports structural, microstructural and dielectric characteristics of Sr 2+ doped PZT (50/50) ceramic. X-ray diffraction reveals that the system exhibit coexistence of two phases (Tetragonal and rhombohedral) at room temperature. Typical relaxor behavior was observed by the dielectric studies and ...  Read More

 Effect Of Ni/NiO Particles On Structure And Crack Propagation In Zirconia Based Composites

I. Danilenko; F. Glazunov; T. Konstantinova; I. Yashchyshyn; V. Burkhovetski; G. Volkova

Volume 5, Issue 8 , August 2014, , Pages 465-471


  The structure formation of yttria stabilized zirconia - nickel oxide composites sintered in air and argon atmosphere were studied. It was shown that the crack propagation in 3Y-TZP ceramics greatly inhibited by creation of composite structure by addition of NiO particles and sintering at 1500 o C in ...  Read More
