“…Tailoring both resistivity and RC constant further by dopants as already demonstrated for other material systems is encouraged for the future. 16,26,27 As already discussed, the reason behind the broad plateau in temperature dependent permittivity appears to be due to two distinct dielectric anomalies that are gradually smeared into each other as KNN content increases. Of course, the physical origin behind these two anomalies has to be clarified in order to fully understand and further optimize these materials.…”

“…The activation energy E a for the electrical conductivity is 0.82 eV ͑9KNN͒, 0.74 eV ͑12KNN͒, 1.04 eV ͑15KNN͒, and 0.77 eV ͑18KNN͒ in the range from 100 to 300°C. At 300°C the resistivity is in the order of magnitude of 10 8 ⍀ m, outperforming PZT5A with 1.9 ϫ 10 7 ⍀ m, 0.36BiScO 3 -0.64PbTiO 3 ͑BSPT64͒ with 2.4 ϫ 10 6 ⍀ m or ͑Pb, Ba͒Nb 2 O 6 with 10 5 ⍀ m. 7,16 The time dependence of a discharging process of a capacitor is determined by the time constant according to Eq. ͑1͒.…”

“…Moreover, BSBT-KBT incorporates the element scandium which is also found in other materials that had been suggested for high-temperature dielectrics. 15,16 The extraordinarily high price of scandium, however, limits the use of such materials to academic research. With regard to a potential application, it is vital to incorporate only those raw materials that are widely available with a reasonable price.…”

The dielectric, electrical and structural properties of (1–x)(0.94Bi1/2Na1/2TiO3–0.06BaTiO3)–xK0.5Na0.5NbO3 (BNT–BT–xKNN) with x=0.09, 0.12, 0.15, and 0.18 were investigated as potential candidates for high-temperature capacitors with a working temperature far beyond 200 °C. Temperature dependent dielectric permittivity (ε) showed two local broad maxima that at the optimal composition of KNN (x=0.18) are combined to form a plateau. This then results in a highly temperature-insensitive permittivity up to ∼300 °C at the expense of a small reduction in absolute permittivity values. High-temperature in situ x-ray diffraction study showed pseudocubic symmetry without obvious structural changes, which implies that the dielectric anomalies observed could only be a consequence of a slight change in space group. BNT–BT–0.18KNN showed a permittivity of ∼2150 at the frequency of 1 kHz at 150 °C with a normalized permittivity ε/ε150 °C varying no more than ±10% from 43 to 319 °C. With very good electrical properties persisting up to 300 °C, i.e., a resistivity on the order of magnitude of 108 Ω m and the RC constant of about 1 s, the examined BNT–BT–xKNN compositions present a good starting point for the development of high-temperature capacitor materials.

Articles you may be interested inEnhanced piezoelectric performance of (0.98-x)Bi(Sc3/4In1/4)O3-xPbTiO3-0.02Pb(Zn1/3Nb2/3)O3 ternary high temperature piezoelectric ceramics (0.95-x)BiScO 3 -xPbTiO 3 -0.05Pb(Cd 1/3 Nb 2/3 )O 3 (BS-xPT-PCN) high temperature piezoelectric ceramics near the morphotropic phase boundary (MPB) have been synthesized by traditional solidstate reaction methods. The microstructural morphology, phase structure, and electrical properties of BS-xPT-PCN ceramics were investigated in detail. X-ray diffraction analysis indicated BS-xPT-PCN ceramics have a pure perovskite structure. The coexistence of rhombohedral and tetragonal phases at MPB composition enhanced the polarizability by the coupling between two dynamically equivalent energy states, resulting in the improved piezoelectric and ferroelectric properties at MPB vicinity. The BS-xPT-PCN (x ¼ 0.60) ceramics possess the optimal piezoelectric and ferroelectric properties with d 33 ¼ 505pC/N, k p ¼ 55.9%, k t ¼ 36.5%, strain ¼ 0.23% (under the electric field 37.5 kV/cm), and P r ¼ 39.7 lC/cm 2 . High temperature dielectric behaviors showed diffuse phase transition in BS-xPT-PCN ceramics. The Curie temperature T c was found to increase from 371 C to 414 C with x increasing from 0.58 to 0.62. All these results together with the good thermal stabilities make the BS-xPT-PCN ceramics promising candidates for high temperature piezoelectric applications. V C 2013 AIP Publishing LLC.

“…It was reported that BiScO 3 -PbTiO 3 based materials exhibited both high Curie temperature and high piezoelectricity, and had the potential for high-temperature piezoelectric actuator applications. [19][20][21] Our previous work showed that a piezoelectric actuator comprised of Mn modified BiScO 3 -PbTiO 3 ceramics operating in first longitudinal (L 1 ) and second bending (B 2 ) vibration modes was able to work at the temperature as high as 200 C. 22 However, the load and speed performances of the piezoelectric actuator dropped dramatically at the temperature above 150 C. For example, the maximum driving force and moving speed at 200 C were only half of that of the piezoelectric actuator at room-temperature. Investigations reflected that the resonance frequency difference between L 1 and B 2 modes of the piezoelectric actuator enlarged with the rise of the temperature, 22 leading to the produced elliptical motion disordered and making its drive performance became worse.…”

Conventionally, piezoelectric ultrasonic linear actuators operate in longitudinal and bending combination (degenerate) modes for producing an elliptic motion which drives a slider moving linearly. With the increasing temperature, the degenerate mode will split into two separated modes again, resulting in piezoelectric actuators working to fail. Here, we report a miniature piezoelectric ultrasonic linear actuator made of Mn modified (1−x)BiScO3–xPbTiO3 piezoelectric ceramics operating in two orthogonal first bending modes (B1-B1). The B1-B1 mode linear actuator showed much better load and speed temperature stability than piezoelectric actuators operating in different combination mode in the investigated temperature range of room temperature to 200 °C.
