The invention relates to a refractory plate for a sliding shutter for regulating a flow rate of liquid steel, to the use of a melt raw material as material in a plate of this kind and to a melt vessel for receiving liquid steel which has a plate of this kind for regulating a flow rate of liquid steel from the melt vessel.

Setter plates are fabricated from Li-stuffed garnet materials having the same, or substantially similar, compositions as a garnet Li-stuffed solid electrolyte. The Li-stuffed garnet setter plates, set forth herein, reduce the evaporation of Li during a sintering treatment step and/or reduce the loss of Li caused by diffusion out of the sintering electrolyte. Li-stuffed garnet setter plates, set forth herein, maintain compositional control over the solid electrolyte during sintering when, upon heating, lithium is prone to diffuse out of the solid electrolyte.
