Ordered, low-structural-state alkali feldspars were equilibrated with K-Na fluoride solutions (total fluoride concentration 0.8 molal) at 450, 500, 600oC at 2000 bar in run times varying from 11 to 40 days. The results are very similar to those of previous workers with alkali chloride solutions. A free-energy difference between Na(aq) and KF(aq) is reported as 8720 + or - 500 calories. -K.F.
