METHOD FOR DOPING AN ALUMINIUM OXIDE CERAMIC

A method for doping an aluminium oxide ceramic involves producing a blank from slurry, removing the technical binder, and firing, wherein, according to the invention, upon removal of the technical binder, the blank is saturated with an aqueous solution of zirconyl nitrate ZrO(NO3)2×2H2O, and is then...

Beschreibung
Zusammenfassung:	A method for doping an aluminium oxide ceramic involves producing a blank from slurry, removing the technical binder, and firing, wherein, according to the invention, upon removal of the technical binder, the blank is saturated with an aqueous solution of zirconyl nitrate ZrO(NO3)2×2H2O, and is then heated, the temperature being increased to 400ºC. Le procédé d'alliage de céramique en oxyde d'alumine comprenant la fabrication d'une ébauche à partir de barbotine, l'élimination du liant technique et le recuit après l'invention ; après l'élimination du liant technique l'ébauche est imprégnée avec une solution aqueuse de nitrate de zirconyle ZrO(NO3)2×2H2O puis chauffée à une température allant jusqu'à 400°C.
