Summary

The changes in the solubility and in the phase composition of yttrium-aluminum garnet (YAG) as a result of its mechanochemical treatment for 2 h in a planetary ball mill together with H3BO3 and Na2CO3 (mole ratio H2BO3/Na2CO3=4) in ratios (H3BO3+Na2CO3)/YAG=2,4, and 9 are studied. At a ratio of 9, the yield of yttrium in the water solution obtained upon treatment of the activated mixture at 90 °C (50 cm3 water/g sample) reaches 85%. Its content in the same solution is above 93% relatively to the sum Y+Al.

Zusammenfassung

Die Änderungen bezüglich Löslichkeit und Phasenzusammensetzung von Yttrium-Aluminium-Granat (YAG) als Ergebnis einer zweistündigen mechanochemischen Behandlung in einer Kugelmühle zusammen mit H3BO3 und Na2CO3 (Molverhältnis H3BO3/Na2CO3=4) bei (H3BO3+Na2CO3)/YAG-Verhältnissen von 2, 4 und 9 wurden untersucht. Bei einem Verhältnis von 9 erreicht die Ausbeute an Yttrium in der wäßrigen Lösung nach Behandlung der aktivierten Mischung bei 90 °C (50 cm3 H2O pro Gramm) 85%. Relativ zur Summe Y+Al beträgt der Yttriumgehalt 93%.
