This study focuses on optimizing and characterizing dielectric materials for MRI (Magnetic Resonance Imaging) applications, emphasizing the preparation and electrical evaluation of MgTiO3-CaTiO3 ceramics. The materials investigated include MgTiO3 ceramics enhanced by adding CaTiO3 in varying concentrations. The sample preparation process involves adapting ceramic powder, typically used for casting, to a uniaxial pressing method. This process includes stages such as powder grinding, binder addition, atomization, sieving, and pressing, followed by sintering to achieve dense ceramic structures. Electrical characterization involves non-destructive and dielectric strength testing using a high-frequency test bench and a vector network analyzer. Silver ink is used for metallization, enabling capacitance measurements, dielectric constant, and loss tangent over a frequency range. The results indicate that adding CaTiO3 to MgTiO3 significantly enhances the dielectric properties, making the ceramics suitable for high-frequency MRI applications. This study identifies the most suitable dielectric material based on electrical performance characteristics, providing valuable insights for improving the design and functionality of MRI systems.
