Notizen: Abstract A gravimetric technique was used to measure the cation vacancy concentration in pure ferrous sulfide and in ferrous sulfide containing small amounts of chromium or manganese. Measurements were made over a wide range of sulfur pressures, defined by H2/H2S mixtures, at 500, 600, and 700°C (723, 823, and 923 K). Chromium was found to increase the defect concentration by an amount consistent with the Wagner-Hauffe model pertaining to aliovalent cations. Also in accord with this model, manganese did not measurably affect the cation vacancy concentration.
