Ito, E., Morooka, K. and Ujike, O. (1993). Dissolution of K in molten iron at high pressure and temperature. Geophysical Research Letters 20: doi: 10.1029/93GL01538. issn: 0094-8276.

Partioning of K between molten iron and silicate melt was examined at about 26 GPa and 2600¿C using a mixture of pure iron and natural microcline as the starting material. The dissolution of K in molten iron up to about 0.2 wt % was confirmed. The distribution coefficient of K between molten iron and silicate melt was about 3.8¿10-2 (atomic ratio). This value suggests the presence of 5 ppm K in the earth's core, yielding 3¿1010 W for the present day heat generation by K. ¿ American Geophysical Union 1993
