Abstract (en)

[origin: WO2022089823A1] The invention relates to a method for producing a compacted component and to an article which comprises a compacted component. In a method for producing a compacted component (10), a starting material (20) at a temperature (T) below 800°C is exposed to an electric field (12). The starting material (20) comprises a first material (14) from the group of cuprates. The method is technically undemanding because compacting is possible without the starting material being heated.
