A manufacturing system includes a tape advancing through the manufacturing system and a station of the manufacturing system. The tape includes a first portion having grains of an inorganic material bound by an organic binder. The station of the manufacturing system receives the first portion of the tape and prepares the tape for sintering by chemically changing the organic binder and/or removing the organic binder from the first portion of the tape, leaving the grains of the inorganic material, to form a second portion of the tape and, at least in part, prepare the tape for sintering.

The method includes the steps of: a) selecting particles with particular slenderness ratios and diameters from SiC powder to serve as selected SiC material powder; b) coating a PVA coating on particles of the selected SiC material powder so that the PVA coating and the selected SiC material powder are combined into a particulate ceramic material; c) pressing the particulate ceramic material into a ceramic base body; d) sintering the ceramic base body to form a fixed shape and forming completely continuous channels from an inside to a surface thereof by cooling; and e) infiltrating the ceramic base body with molten aluminum. The ceramic composite material made by the method includes a ceramic base body having completely continuous channels from an inside to a surface thereof; an aluminum filler filled in the channels; and an aluminum coating disposed on the ceramic base body and integratedly connecting with the aluminum filler.

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.
