The solubility of ZnAl 2 O 4 (gahnite spinel) and NZOI (corundum) in their respective molten PbF 2 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/ PbF 2 weight ratio) at 1200°C were 0.151 for A1 2 O 3 and 0.108 for ZnAl 2 O 4 , 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.
