Glass-ceramics containing Fresnoite crystals: a potential piezoelectric material for Surface Acoustic Waves generation at high temperatures

Marie-Sophie Renoirt

University of Mons (UMONS)

I am Research and Teaching Assistant at the University of Mons (Engineering Faculty), in the field of Engineering and technology. I have beginning my PhD thesis in 2014, after realising a Master's degree in Chemistry and Material Science at University of Mons (Science Faculty). The subject of my PhD thesis is the potential of glass-ceramics containing fresnoite crystals to generate Surface Acoustic Waves. Therefore, I am working on piezoelectric ceramics and their properties, in the aim of sensors elaboration. In the same time, I supervise students during pratical works linked to material science (Rheology, Thermodynamic, Chemistry,...).


Most of current piezoelectric sensors are based on ferroelectric ceramics. Nevertheless, the use of ferroelectrics is limited in temperature due to a rapid depolarisation over time, when approaching the Curie temperature.... [ view full abstract ]
