Claim 11:
12. A method of making the composite ceramic, comprising:
a first mixing of inorganic source materials to form a mixture, including a lithium source compound and at least one transition metal compound;
a first milling of the mixture to reduce the particle size of the precursors;
calcining the milled mixture to form a garnet oxide at from 800 to 1200° C.;
a second mixing of the milled and calcined garnet oxide with at least one minor phase additive to form a second mixture;
a second milling of the second mixture to reduce the particle size of constituents of the second mixture;
compacting the second milled second mixture into a green pellet; and
sintering the green pellet at a temperature ranging from 1000° C. to 1300° C.,
wherein the minor phase additive comprises LixTiO(x+4)/2, with 0.66≤x≤4.
