The paper presents the results of an investigation of the nickel density and thermal expansion over the temperature range from 145 K to 2030 K. The measurements have been carried out by using the dilatometer method and the
γ
-ray attenuation technique (gamma method). The errors of the density and coefficients of thermal expansion measurements are estimated to be within 0.05 % to 0.25 % and 1 % to 2.5 %, respectively. The accuracy of determination of the volumetric thermal expansion coefficient of the melt by the
γ
-ray attenuation technique is substantiated. The density change on melting (
4.70
±
0.15
) % has been directly measured. The temperature dependences and reference tables of the volumetric properties of solid and liquid nickel have been developed. A comparison of the obtained results with literature data has been made.
