The influence of alumina sources on the phase compositions, microstructure and thermal conductivity of the samples was investigated. The mechanism of the in-situ synthesis of Al₂TiO₅ was discussed in detail. The results showed that increasing the sintering temperature was beneficial for the formation of Al₂TiO₅. Besides, adding white fused corundum or tabular corundum was conducive to the preparation of Al₂TiO₅. The liquid phase formed by a small number of impurities in the raw materials at high temperatures could accelerate the diffusion velocity of Al³⁺ and Ti⁴⁺, which was beneficial to the formation of Al₂TiO₅ and the stability of its structure. The sample with tabular corundum sintered at 1600 °C had the highest content of Al₂TiO₅ about 86 wt%, and the largest average grain size of 35.3 μm. It also showed satisfactory performance, with the bulk density of 2.99 g/cm³ and the compressive strength of 98.5 MPa.

Among these materials, bismuth titanate-ferrite (Bi₅Ti₃FeO₁₅) stands out as a prominent candidate for high-temperature piezoelectric applications, given its elevated Curie temperature (<i>T</i>_C) of 760 °C. Despite its potential, the practical utilization of Bi₅Ti₃FeO₁₅ in high-temperature piezoelectric devices is limited by low resistance at elevated temperatures and poor piezoelectric performance. To address these issues, we explored a composition optimization strategy involving the partial substitution of bismuth ions with rare-earth dysprosium (Dy) ions to enhance piezoelectric performance and direct-current (DC) electrical resistivity of Bi₅Ti₃FeO₁₅. This substitution aims to mitigate the volatility of bismuth ions and stabilize the (Bi₂O₂)²⁺ layer, thereby reducing oxygen vacancy concentration. We successfully synthesized Bi_5-<i>x</i>Dy_<i>x</i>Ti₃FeO₁₅ (BTF-100<i>x</i>Dy) oxide compounds using a solid-state reaction method. Our experimental results demonstrate that dysprosium-substituted Bi₅Ti₃FeO₁₅ exhibits markedly enhanced piezoelectric performance compared to the unmodified Bi₅Ti₃FeO₁₅. Specifically, the BTF-5Dy composition achieved a significant increase in the piezoelectric constant (<i>d</i>₃₃) to 23.1 pC/N, which is approximately three times higher than that of the unmodified Bi₅Ti₃FeO₁₅ (7.1 pC/N). The temperature-dependent measurements of DC electrical resistivity revealed that dysprosium substitution substantially improves the material’s electrical resistivity at elevated temperatures. Additionally, BTF-5Dy exhibited a high <i>T</i>_C of 787 °C, a low dielectric loss tan<i>δ</i> (~ 0.38% at 1 MHz), and good thermal stability of electromechanical properties up to 300 °C. These improvements are attributed to lattice distortion and reduced oxygen vacancies. Collectively, these findings suggest that dysprosium-substituted Bi₅Ti₃FeO₁₅ ceramics hold great promise as high-performance materials for high-temperature piezoelectric applications.</p></div>","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"61 4","pages":"1571 - 1582"},"PeriodicalIF":2.1,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144929353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The combustion product was crushed and sieved in order to recover the fractions less than 40 µm.

X-ray diffraction analysis of the samples revealed the presence of TiC, Al₂O₃ and Al₂TiO₅ spinel. The combustion in open-air is accompanied by an evaporation of aluminum, the presence of unreduced TiO₂ and the formation of new oxides such as Ti₃O₅ and Ti₄O₇ which generate Al₂TiO₅ spinel during the sintering. Microstructural analyses using a scanning electron microscope combined with semi-quantitative evaluation revealed the basic ceramic structure composed of TiC, Al₂O₃ and Al₂TiO₅.

FS experiments were conducted under 20, 25, and 30 V/mm electric fields. CISW was sintered using the FS method resulting in lower temperatures and shorter processing times, thus yielding energy savings. Through this method, it was observed that the interatomic spaces narrowed due to the electric field and temperature applied to the sample. Physical, chemical, and mechanical tests (3-point bending and hardness) were carried out on all sintered materials. Experimental results indicated that the sample sintered under the 20 V/mm electric field at 517ºC for 15 s exhibited better mechanical properties compared to CS. On the other hand, the sample flash sintered under 30 V/mm electric field had lower temperatures (478ºC) compared to all FS processes that were carried out with perfect intergranular interactions. However, the mechanical properties were lower than the others because the structures may have passed into the liquid phase.
