Abstract

sponsored_project_image

The aim of this proposal is to develop high Curie temperature lead free piezoceramics with superior piezoelectric properties. It is of our national importance to design, develop and scale up high Curie temperature lead free piezoceramics with superior piezoelectric properties. PI and his group will contribute to this through improvements, reliability and by improving the understanding of high Curie temperature lead free piezoceramics. Further impact derives from the training of early career researchers, employed in this project, who will provide the skills to transfer high Curie temperature lead free piezoceramics based technologies from academia to industry.

In this project, we will achieve the following goals:

Curie temperature upto 450°C in chemically modified lead free BiFeO3-BaTiO3 solid solutions
piezoelectric coefficient upto 200 pC/N in chemically modified lead free BiFeO3-BaTiO3 solid solutions
A prototype piezoelectric vibration sensor (demonstration only) will be designed in consultation with domain scientist.

The project will also be benefitted from applicant’s existing links and joint research activities with Dr. O.P. Thakur, SSPL-DRDO, Prof. Rajeev Ranjan, Materials Engineering, IISc Bangalore, Prof. Ashish Garg, Materials Science and Engineering, IIT Kanpur and Dr. A.R. James, DMRL-DRDO.
