The stopping power for heavy ions in several ionized materials is determined over a range of densities and temperatures using a generalized stopping-power formula and an effective charge chosen to give an agreement with stopping power in cold materials. The stopping power can be increased or decreased relative to cold material, depending on the atomic number, the density, temperature, and ion energy.
