Claim 26:
27. A method for depositing lithium garnet material, the method comprising:
providing components of lithium conducting ceramic powder material at a first quantity, the components being characterized by a first density, the components being characterized by a median particle size of about 100 nm to 10 μm;
providing a first flux material at a second quantity, the first quantity being more than 100% of the second quantity, the first flux material comprising inorganic salts of lithium material, the first flux material being characterized by a melting temperature of about 500-1000° C.;
providing a second flux material at a third quantity, the second flux material being characterized by a melting temperature of about 500-1000° C.;
mixing the first flux material and the second flux material with the components to form a eutectic mixture;
mixing the eutectic mixture with the lithium conducting ceramic powder material to form a fluxed ceramic powder material;
shaping the fluxed ceramic powder material into a predetermined shape;
flux sintering the shaped fluxed ceramic powder material; and
forming a dense lithium conducting material, the dense lithium conducting material being characterized by a second density, the second density is at least 20% higher than the first density.
