Thermoelectric materials are designed according to thermoelectric characteristics, which require good agreement with the Zeebeck coefficient, electronic conductivity, and thermal conductivity. This paper is presented the comparative data of thermal properties in five compounds of nanocrystalline copper sulfides KxCu1.85S (0<x <0.05) at the temperature zone from 300 K to 700 K. X-ray phase analysis shows a mixture different phases of copper sulfides such as Сu1.85S cubic phase, Cu2S cubic phase, Cu17S9 (Cu1.89S) rhombohedral phase, Cu2S tetragonal phase  in all investigated compounds at room temperature. The sizes of crystallites in the alloys estimated from half-width of X-ray lines are in range from 24 to 90 nm. The thermal conductivity of alloys decreases to 0.2 ÷ 0.6 W K-1m-1 in temperature range of 350 – 700 K due to increasing of the amount of potassium (for x = 0.04, 0.05). This guides the maximum thermoelectric characteristics of the material. The obtained results are important for semiconductor materials used in the field of thermoelectric devices.
