1. A method for forming a dense lithium conducting material, the method comprising:
providing a lithium conducting ceramic powder material at a first quantity, the ceramic powder material being characterized by a first density, the lithium conducting ceramic powder material being characterized by a median particle size of about 100 nm to 10 μm;
providing a first flux material at a second quantity, the second quantity being less than 51% of the first quantity, the first flux material comprising 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 at least the first flux material and the second flux material to form a eutectic mixture;
mixing the eutectic mixture with the lithium conducting ceramic powder material to form a fluxed ceramic powder material;
flux sintering the shaped fluxed ceramic powder material to a temperature of less than 1100° C.; 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.
