BaTiO3 powders prepared by electric discharge
assisted mechanical milling (EDAMM) method
Monika Wyszomirska
University of Wollongong, Australia
Over the years electric discharge assisted mechanical milling
device had proven to be fast and extremely effective method
for powders processing and synthesis . Thus, as a next step an
in-depth analysis of the products was performed to define the
processes that govern specific compounds formation. In this work
we present low and high temperature BaTiO3 perovskite phases
depending on processing conditions used. As characterization
techniques scanning electron microscope was used to visualize
grains morphologies of prepared disc-shaped samples and
to define the regions of final and intermediate products.
elemental analysis using backscattered electron detector and
aztec software was also performed. EBSD system being part
of the abovementioned Microscope was utilized to prove the
crystallographic structure and quantify the constituent phases.
additionally, transmission electron microscopy was performed
to observe the grain boundaries of specific regions on the samples
prepared by focused ion beam instrument. Described procedures
are meant to provide extensive crystallographic information
which will be used to define the growth mechanism of specific
phases in BaTiO3 under different EDAMM conditions.
Biography
Monika Wyszomirska graduated from a master's of materials engineering
degree at Warsaw University of Technology, Poland in 2013. Since then she has
been involved in doctoral studies at University of Wollongong, Australia. Monika
is presently working on plasma processing of ceramic powders with special
interest placed on phase transformations during pulsed plasma processing. Her
aim is to broaden then understanding of the processes occurring during Electric
discharge assisted mechanical Milling (EDAMM) therefore leading to more efficient
and optimization of the processing parameters. She is also heavily involved in
materials characterization by X-ray diffraction, secondary and transmission electron
microscopy and especially interested in sample preparations by FIB-SEM.
