The density and thermal expansion coefficients of liquid potassium–lead alloys (30.01, 39.99, 50.00, 66.66, 84.40, and 90.70 at. % Pb) have been determined using gamma-ray attenuation technique over the temperature range from liquidus line to 975 K. The experimental uncertainty of the density measurement is estimated to be within ±0.2–0.4 %. A comparison of the obtained results with literature data has been made. Temperature and concentration dependences of the volumetric properties of liquid K–Pb system have been built and analyzed.
