strontium titanate (BST) or Ba1-xSrxTiO3 with
x=0-1 possesses superior dielectric properties, which are widely used in many
applications like in communication technology, electronic instrumentations, and
various electrical devices. In this paper, the characterization of the
particle and crystallite size of Ba1-xSrxTiO3 (x: 0; 0.3; 0.7) is
described. A two-step refinement commenced: first by mechanical
milling, and then a further refinement under ultrasonic irradiation in a high
power sonicator was applied to Ba1-xSrxTiO3 (x: 0; 0.3; 0.7)
particles. The crystalline powders were obtained through
mechanically alloyed standard research grade BaCO3, TiO2,
and SrCO3
precursors in a planetary ball mill.The powders were first found heavily
deformed after 60 hours of milling and then went through a sintering process at
1200°C for 4 hours to form multicrystallite particles. The presence of a single
phase in the three samples was solidly confirmed in their respective X-ray
diffraction (XRD) patterns. The changes of multicrystallite particles into
monocrystallite particles were obtained only after crystalline powders were
irradiated ultrasonically in a high power sonicator. The processing variable
during ultrasonic irradiation was limited to the duration time of irradiation
and particle concentration in the exposed media. It is shown that
the average sizes of BST particles at x=0; 0.3; 0.7 before ultrasonic irradiation were 353, 348, and 385 nm,
respectively. These respective sizes decreased drastically to 52, 35,
and 49 nm, respectively, after 12 hours of ultrasonic irradiation. These
particle sizes are almost identical with that of their crystallite size. Hence,
the synthesis of monocrystallite particles has been achieved. As the particle
concentration of media takes effect, it is shown that an exposed media with a
higher particle concentration tends to form multicrystallite particles. |
