To clarify the effect of the presence of H_2O on the oxidative decomposition of CaS by O_2, decompositions of CaS with ^<16>O_2 and/or H_2^<18>O were studied using a mass spectrometer. The decomposition of CaS in the presence of both O_2 and H_2O occurred at lower temperature than that in the presence of either H_2O or O_2. From the experimental results using isotopic method, it was confirmed that the contribution of H_2O to the decomposition of CaS in the presence of O_2 was almost constant in the temperature range from 800 to 1000℃.
