Abstract
Lithium-containing polycrystalline ceramic sheets include grains having an average grain size of less than 5 μm, a relative density greater than 90%, and a thickness of up to 200 μm. In aspects, the lithium-containing polycrystalline ceramic sheets include an outer edge of the sheet that has no height variations greater than 1 mm from baseline in a perimeter trace. In aspects, the lithium-containing polycrystalline ceramic sheets include microstructural features of an outer edge of the sheet are no greater than about ⅓ the thickness of the sheet. In aspects, the lithium-containing polycrystalline ceramic sheets include an outer edge of the sheet that is enriched in lithium relative to a bulk of the sheet.
