Doping procedure for sintering alpha alumina and alpha-alumina material polycrystalline.

摘要

Doping procedure for sintering alpha-alumina material polycrystalline alpha-alumina.; The present invention relates to a method of doping a sintering alpha alumina comprising the steps of:; to. Preparing a slurry of alpha alumina powder in {} Hskip0.3cm a solvent, which is kept under stirring,; b. Add a solution of aluminum alkoxide, as {} Dopant hskip0.3cm, in inert atmosphere,; c. Drying to remove the solvent to a powder {} Hskip0.3cm dry, sieved and calcined,; d. Attrition milling the calcined powder, drying and ta- {} Hskip0.3cm mizado,; and. Obtaining green body by any of {} Hskip0.3cm existing techniques, preferably formed {} Hskip0.3cm by cold isostatic pressing, and; F. Sintering green body obtained in the oven,; and material used polycrystalline alpha alumina to manufacture optical components or structural technical ceramics.
