Tuluk, A. (author), van der Zwaag, S. (author)In this work, we investigated the piezoelectric properties of BiFeO3-rich (1 − (y + x)) BiFeO3–y PbTiO3–x SrTiO3 (0.1 ≤ x ≤ 0.35; 0.1 ≤ y ≤ 0.3) bulk piezoceramics, as this system could potentially lead to the development of bulk piezoelectric ceramics that are suitable for high-temperature applications (>200 °C). Samples with various levels...journal article 2023

Tuluk, A. (author), Brouwer, J.C. (author), van der Zwaag, S. (author)BiFeO <sub>3</sub> is a multiferroic material with a perovskite structure that has a lot of potential for use in sensors and transducers. However, obtaining pure single-phase BiFeO <sub>3</sub> ceramic with a low electrical conductivity via solid-state reactions remains a problem that limits its application. In this work, the suppression of...journal article 2022

Tuluk, A. (author), Mahon, T.R. (author), van der Zwaag, S. (author), Groen, W.A. (author)BiFeO<sub>3</sub> is an interesting multiferroic material with potential use in sensors and transducers. However, the high coercive field and low dielectric strength of this material make the poling process extremely difficult. Poling becomes a lot easier if the ceramic particles are incorporated in a non-conductive polymer with comparable...journal article 2021

Tuluk, A. (author), Mahon, T.R. (author), van der Zwaag, S. (author), Groen, W.A. (author)BiFeO<sub>3</sub> is a multiferroic material with the perovskite structure which is promising for use in sensors and transducers. Single phase production of BiFeO<sub>3</sub> remains a challenge, however. In this study, the optimal calcination temperature to obtain close to single phase powder was determined to be 750°C. The sintering...conference paper 2019
