The Curie point temperature of Ba(Ti1−x Zr x )O3 solid solutions
The Curie point temperature of solid solutions made by firing mixtures of BaTiO 3 and BaZrO 3 powders was found to depend markedly on sintering...

Interface Effects of Laser Ablated and Sputtered High Tc Superconducting Thin Films
High T c superconducting thin films were prepared by DC triode sputtering and laser ablation. With both deposition methods we were able to fabricate...

Ferroelectric Curie points at perovskite-type oxides
The covalent bond energy of the A-O bonding and the enthalpy of formation for perovskite-type oxides ABO 3 were found to show high correlations with...

Flux-sintered BaTiO3 dielectrics
BaTiO 3 modified with BaZrO 3 or SrZrO 3 was sintered at 1100° C with the aid of various fluxes. The objective was to identify compositions in the...

Chemical mitigation of the transmutation problem in crystalline nuclear waste radiophases
Certain deleterious effects on a solid nuclear waste form, though not yet quantitatively defined, could occur due to transmutations of the type 137 Cs + ...

Fusibility diagram of the BaAl2O4-Ba2SiO4-BaZrO3 system
New types of cement were developed from the BaAl 2 O 4 -Ba 2 SiO 4 -BaZrO 3 system. The cements are characterized by high refractoriness (over 1800°C) and...

Some problems in the technology of translucent Y2O3 ceramics
The degree of translucence of Y 2 O 3 ceramics depends on the amount of additive, the grinding time of the components, and the calcination temperature...

The resistance of refractories to molten barium
Refractories processed from corundum, magnesia-alumina spinel, periclase, and calcium and barium zirconates exhibit good resistance to the action of...

Non-elastic mechanical behaviour in SrZrO3 by reorientation
The crystal structure of different phases in (Ca-Sr)ZrO 3 and (Sr-Ba)ZrO 3 was studied with X-ray diffractometry. One orthorhombic phase, two...
