Abstract: A method of converting a feed solid polycrystalline of alumina into a hydronium conductor requires the preselection of an appropriate feed ceramic preferably with a chemical forumula;
and with a t(S) of 0.37 ± 0.03 wherein
The crystallographic lattice is altered by placing the solid feed ceramic in an ionic solution or melt containing two or more ionic species of different ionic radii; the composition of the melt or solution being written: M,, M 2 (M 3 ...) X where M, and M 2 (and M 3 etc.) are ions of dissimilar size and as examples sodium, potassium, lithium and hydronium ions. After a time the material is removed, washed and subjected to a field effect exchange whereby the desired hydronium conducting solid ceramic having the following chemical composition is achieved;
where (a) (b) (c) = 0→I and a + b + c = I and Z is a stabilizer of the β" phase.

Abstract: A polymorph which has a high conductivity for protons (H + ) in the form of hydronium ions (H 3 0 + ) is achievable with the compound known as H 3 O + -β"-Al 2 O 3 via the direct production of a dense K + -β"-Al 2 O 3 material with a high percentage (80% or more by weight) of the β"- alumina phase. That phase is ion exchangeable with the hydronium ion. A method of producing such potassium β"alumina discloses utilizing as constituent feed components compounds of sodium, potassium, magnesium, and aluminum, freezing them then freeze-drying them and calcinating them. The resultant is K+β"-Al 2 O 3 in an ultra-fine white powder form. The potassium ion (K + ) of the compound is readily ion exchangeable with H 3 0 +.
