Electrical properties of A′Ca2Nb3O10 (A′=K, Rb, Cs) layered perovskite ceramics
Ionics, 2001 The electrical conductivity properties of Dion-Jacobson type layered perovskites A′Ca2Nb3O10 (A′=K, Rb, Cs) was investigated under different gas atmospheres. An increase in the electrical conductivity by about 2–5 orders in magnitude in both ammonia and hydrogen atmospheres is observed compared to air. Among the members of the series, the compound with

Hot-pressed (Pb, RA(ZR, Ti, RB)O3 ferroelectric ceramics for electro-optic applications
Ferroelectrics, 1976 Abstract This paper reports the effects of new substitutional ions on achieving optically transparent hot-pressed lead zirconate titanate ceramics. The effects of both single ion substitution and simultaneous substitution of different ions at A and B sites were examined. In single ion substitution, the experimental results were negative.

Ceramics International, 2019 Abstract Reaction bonded silicon carbide (RB-SiC) ceramics are the primary structure and mold materials for the optical industry and mostly are machined by means of ultra-precision grinding to achieve a satisfactory surface quality. However, it is not easy to attain the theoretical prediction of surface quality, particularly surface roughness ...

Magnetic properties and surface resistance of Rb-doped YBaCuO ceramic
IEEE Transactions on Magnetics, 1994The influence of Rb/sub 2/CO/sub 3/ additive on the properties of YBCO was investigated. The impurity was added to the usual stoichiometry of Y/sub 1/Ba/sub 2/Cu/sub 3/O/sub y/ to produce an initial batch with general formula Y/sub 1/Ba/sub 2/Cu/sub 3/(Rb)/sub x/O/sub y/ where x=0 to 0.60.

Enhanced electrical properties in Rb-substituted sodium bismuth titanate ceramics
Applied Physics A, 2016Influence of large ionic radius cation rubidium (Rb) substitution in the A-site of sodium bismuth titanate (NBT) on remnant polarization and dielectric constant is investigated. Substitution of 0.01 mole fraction of Rb in NBT ceramics escalates remnant polarization and dielectric constant coupled with reduction in coercive field and enhanced ...
