The effect of the temperature and time of spark plasma sintering (SPS) of a nickel powder on the structure of obtained samples of porous nickel was studied, and their mechanical strength under compression was evaluated. Based on the results of the experiments, it was found that spark plasma sintering the nickel powder at a temperature of 480°C with a holding time of 4 minutes enables to obtain samples with a porosity of 78.8%, having a structural performance and a compressive strength exceeding 1 MPa.
