Popis:	The thermotransport of 85Sr and 54Mn tracers in single crystals of KCl was measured in the temperature range 950–1025 K, by means of Soret effect measurements. The mean value of the impurity heat of transport was −3.18±0.09 eV for Sr in pure or Sr‐doped crystals, and was −5.45±0.83 eV for Mn in pure or Mn‐doped crystals. There was no significant difference between values from pure and doped crystals for Sr, but for Mn this may not be the case. A discussion of the experimental and theoretical limitations of such measurements as a source of information about the heats of transport for individual jumps was given, and a comparison made with earlier thermotransport measurements in simple ionic solids.
