In recent years the progress in Room Temperature Fabrication (RTF) method ofelectroceramics has been fast. This includes ferrites and dielectrics which electrical properties can be adjusted showing feasibility to high frequency applications. Since no sintering is required, 2D and 3D printed structures have been also introduced. Very recently RTF have been utilized also for so called„upside-down“ composites with ferroelectric and piezoelectric performance, as well as to ultra low permittivity dielectric feasible for advanced antenna systems for 5G networks. This presentation surveys all compositions realized so far with the RTF dicussing their electrical properties, advantages and disadvatages, and demonstrated devices.
