For my senior research project, I am studying the mechanical properties of Ferroelastic ceramics, to determine how various dopants affect the strength of Piezoelectrics.

Doped and un-doped Sodium Bismuth Titanate (NBT) and Lead Zirconate Titanate (PZT) samples were processed using slip and tape casting.Samples were polished to allow for accurate hardness measurement. I then compared the various dopants used with NBT and PZT to determine the varying effects on the mechanical properties.

During my time working with this research group, I also learned to use an X-ray Diffractometer (XRD), Ramen Spectrometer, Foruier Transform Infrared Spectrometer (FTIR), and Atomic Force Microscopy (AFM) to characterize materials.
