Abstract |
|
|
| This study investigates the influence of sintering temperatures on the mechanical properties of Ba1-xSrxTiO3 ceramics. Ba1-xSrxTiO3(x=0.2) ceramics are synthesized via Sol-Gel and sintered at varying temperatures. We use the appropriate testing methods to describe mechanical qualities like hardness, fracture toughness, and elastic modulus. The results show that the mechanical behavior changes a lot when the sintering temperature changes. This shows how important processing conditions are for customizing the mechanical performance of Ba1-xSrxTiO3 ceramics that could be used in advanced electronic and structural materials. XRD pattern exhibited a tetragonal phase, and the crystal size increased with increasing sintering temperature. The BST samples surface morphology appears uniform and homogeneous, with moderate sintering temperatures. High Sintering Temperature, and higher density as the material achieves better grain growth and packing, reducing porosity. High Sintering Temperature increases mechanical strength due to improved densification and reduced porosity, producing higher hardness because of increased density and larger, well-formed grains and improved fracture toughness as the material becomes denser and grain boundaries are better formed, enhancing crack resistance. Also, (c/a ratio) was found to decrease with an increase in sintering temperatures.
