• Oxygen solubility in Na-K (22w/o-78w/o) was determined by a vacuum distillation method. A NaK sampling apparatus was installed in a forced convection NaK loop with a cold trap. Subtracting the oxygen blank from oxygen amount calculated from chemically determined quantities of Na and K in the distillation residue and using the least squares method, a following equation for oxygen solubility in NaK over a temperature range of 90210°C was derived<BR>log<SUB>10</SUB><I>S</I>=7.09-2, 795/<I>T</I>, <BR>where <I>S</I> is the oxygen solubility (wppm) and <I>T</I> the absolute temperature (K). This equa-tion was close to those derived for oxygen solubility in Na.
