Aliovalent dopant codoped rutile-TiO materials have garnered attention due to their excellent performance properties, characterized by low loss tangent (tanδ), high dielectric permittivity (ε'), and stable ε' over a broad temperature range. This performance is primarily due to the electron-pinned defect-dipoles (EPDDs) of the complex defects [Formula: see text]Ti-[Formula: see text]TiB. Notably, the excellent dielectric properties in ZrTaTiO (Zr-TTO) ceramics can be achieved using the traditional mixed oxide method without the EPDDs, due to the absence of A (acceptor doping ions).

With the rapid development of electronic information technology, dielectric ceramics are widely used in the field of passive devices such as multi-layer ceramic capacitors. In this paper, (BiW)TiO (BWTO) ceramics with superior dielectric properties have been prepared by using a traditional solid-state method. Remarkably, at a (BiW) doping level of 0.

Commercially available LaFeO powder was processed using the spark plasma sintering (SPS) technique. The results of the dielectric measurement showed high permittivity, but this was strongly frequency-dependent and was also accompanied by a high loss tangent. The chemical purity of the powder and changes induced by the SPS process influenced the stability of the dielectric parameters of the bulk compacts.
