Abstract (en)

[origin: WO2016096870A1] The invention relates to a carrier plate, wherein a first ceramic functional layer is braced by a ceramic stressing layer (SPS) via a connecting layer (VS) in order to reduce the lateral sintering shrinkage. The functional layer (FS) and the stressing layer (SPS) are glass-free or have an only slight glass content of less than 5 wt%, while the connecting layer (VS) comprises a glass component or is a glass layer.
