Production of beta-alumina

摘要

A method of producing a beta-alumina ceramic article containing a doping addition of magnesium oxide or of magnesium oxide and lithium oxide, comprising the steps of wet-milling a precursor material or emulsification of an already powdered precursor material to form an aqueous slurry, spray-drying the slurry to produce a powder, forming the powder into a green shape and sintering the shape, wherein the precursor material contains at least some of the magnesium oxide in the form of magnesium aluminate.
