Description
Summary:Ferroelectric materials have found many applications in a wide range of capacitors, transducers, sensors, light valves and motors. Their properties are related to the routes they are processed. Ferroelectric materials in their bulk polycrystalline form are difficult to fabricate in shapes and sizes suitable for device applications. This is due to cracking occurs during sintering process. This has lead to research being undertaken to produce a crack free dense polycrystalline ferroelectric samples by using additives. Therefore in this study PbTiO2 powders with addition of SiO2 as an additive were synthesized by solid-state reactions using different SiO2:PbTiO3 weight ratios (0.1:0.9, 0.05:0.95 and 0.03:0.97). Structural and morphological changes were studied using XRD and SEM with regard to after the addition of SiO2 at sintering temperatures 900 °C, 1000 °C and 1100 °C.
