The OPARA service was recently upgraded to a new technical platform. You are visiting the outdated OPARA website. Please use for new data submissions. Previously stored data will be migrated in near future and then the old version of OPARA will finally be shut down. Existing DOIs for data publications remain valid.

In this study, ultrasonic decoating is investigated as a recycling process for solid oxide cells (SOC). SOC are mainly particle-based oxide ceramics and have a layer structure in the micrometer range. Critical raw materials such as nickel and various rare earth elements are present in high concentration in these layers. Based on the layer structure, the selective decoating approach has proven to be suitable for recovering very highly concentrated material streams without the need for complex separation processes. In ultrasonic decoating, the load is introduced on one side via a sonotrode. This leads to a preferential detachment of the stressed side. Ultrasonic decoating can be used to selectively separate the oxygen side layers of SOC.

This project is open access and publicly accessible.
