Recent Research on Piezoelectric Ceramics

Dear Colleagues,

Piezoelectric materials are widely used in various electronic devices, such as capacitors, sensors, transducers, thermistors, and actuators, due to their ability to interconvert mechanical and electrical energy. For these advanced applications, piezoceramics with good electrical properties can be prepared using methods such as solid-state reaction, sol–gel, hot-pressing, two-step sintering, and so on. Manufacturing technologies have attracted a lot of attention in recent decades, but they pose a great challenge in the quality and property of piezoceramics. Defects, oxygen vacancy, and uniform grain distribution easily occur during the preparation process. Understanding the electrical properties, determining defect evolution and grain growth mechanisms at the micro- and nano-scales, exploring innovative preparation technology, and optimizing preparation process parameters are of great significance to achieve piezoceramics with high electricity and temperature stability. This Special Issue aims to summarize frontier research on processing and electrical characterization of various piezoceramics. The scope of this Special Issue includes but is not limited to

• Manufacture technologies of piezoceramics;
• Piezoelectricity;
• Ferroelectricity;
• Defects and oxygen vacancy;
• Grain;
• Electric property characterization.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Crystals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
