Influence of zinc oxide addition on LnTiTaO6 (Ln = Pr, Sm and Dy) materials for dielectric resonators

Padma Kumar, H; Joseph, J T; Thomas, J K; Manoj Raama Varma; Annamma, J; Sam Solomon (Elsevier, 2007)

LnTiTaO6 ceramics, doped with ZnO, were prepared in the solid-state ceramic route. The cylindrical samples were sintered at temperatures between 1360 and 1575 ◦C. The densities were measured using Archimedes method. Samples ...
Microwave dielectric properties of novel lithium containing pyrochlore type oxides: Li3Sm3-xBixTi7Nb2O25 (x=0, 1, 2 or 3)

Prabhakar Rao, P; Ravindran Nair, K; Peter Koshy; Vaidyan, V K (Elsevier, 2007)

Microwave dielectric properties of novel lithium ion containing pyrochlore type oxides: Li3Sm3-xBixTi7Nb2O25 (x=0, 1, 2 or 3) have been reported in this paper. Powder X-ray diffraction patterns show that these oxides have ...
New family of dielectric materials in ca-y-ti-nb-o system having pyrochlore type structure

Nair, K R; Prabhakar Rao, P; Anupama, V R; Joseph, S K; Chandran, M R; Peter Koshy (Blackwell Publishing, 2007)

A new family of pyrochlore-type oxides in the Ca-Y-Ti-Nb-O system has been prepared by the conventional solid-state route. These compounds have a dielectric constant (K) in the range 27-92 and, further, the dielectric ...
Solid state and solution synthesis of Ba(Mg1/3Ta2/3)O-3: A comparative study

Surendran, K P; Rajath Varma, P C; Manoj Raama Varma (Elsevier, 2007)

Ba(Mg1/3Ta2/3)O-3 [BMT] dielectric ceramics are prepared by solid state (one step, two step and molten salt synthesis) and wet chemical methods (precipitation, citrate gel and sol-gel). The formation mechanism of BMT in ...
Synthesis, crystal structure, dielectric properties, and potential use of nanocrystalline complex perovskite ceramic oxide Ba2ErZrO 5.5

Jose, R; Asha, M J; Thomas, J K; Jose James; Jacob Koshy; Divakar, R; Mohandas, E (Elsevier, 2007)

A new member belongs to Ba2REZrO5.5 (RE = Rare-Earth) perovskites, viz. Ba2ErZrO5.5, is synthesized as nanocrystals using a combustion process. Unlike the other Ba2REZrO5.5 perovskites, which are cubic, Ba2ErZrO5.5 ...
