Dielectric Properties of Lead·Strontium Titanate

Advances in Thermodynamics of Ferroelectric Phase Transitions

“…In order to compare it with the experiments, we make use of the following values which are about PbTiO 3 crystal: ρ =7.1g/cm 3 [16], l =900cal/mol [17], k fer =8.8 × 10 5 erg/cm s K [18]. The value of the velocity of the interface's fast motion, which has been measured in the experiments, is 0.5mm/s [11].…”

Non-Equilibrium Thermodynamics of Ferroelectric Phase Transitions

“…In order to compare it with experiments, we make use of the following values which are about PbTiO 3 crystal: ρ =7.1g/cm 3 (Chewasatn & Milne, 1994), l =900cal/mol (Nomura & Sawada, 1955), fer k =8.8 × 10 5 erg/cm﹒s﹒K (Mante & Volger, 1967). The value of the velocity of the interface's fast motion, which has been measured by the experiments, is 0.5mm/s (Dec, 1988).…”

Ferroelectric and Incipient Ferroelectric Properties of a Novel Sr9−xPbxCe2Ti2O36(x = 0−9) Ceramic System

“…It was possible to reduce τ f , but ε' was simultaneously drastically reduced. Only in the case of solid solutions with ferroelectrics (like BaTiO 3 or PbTiO 3 ) 11,12 it was possible to enhance permittivity at room temperature, but simultaneously τ f and the dielectric loss ε'' dramatically rose up. In spite of this, Ba 1-x Sr x TiO 3 is nowadays the most used material in MW tunable devices thanks to its high and tunable ε' and its moderately low ε''.…”
