Abstract

The solubility of ZnAl2O4 (gahnite spinel) and NZOI (corundum) in their respective molten PbF2 solutions was determined by a sealed‐tube quenching method between 900° and 1250°C. Differential thermal analysis was used below 900°C. The solubilities (crystal‐constituent/ PbF2 weight ratio) at 1200°C were 0.151 for A12O3 and 0.108 for ZnAl2O4, whereas at 900°C they were 0.093 and 0.048, respectively. These results are compared with those of single‐crystal growth experiments and the crystalline products are described. Copyright © 1964, Wiley Blackwell. All rights reserved
