Abstract

The reaction to form a mixed sulfide, BaZrS3, was studied using the mixture 0.9BaS+0.1BaCl2+ZrS2+αS (α=0.5, 1.0, 1.5 and 2.0) in evacuated glass ampoules with the reaction time ranging from 10 min to 168 h. At 723 K, the reaction was slow, and the mole fraction of BaZrS3 started to increase after 12 h. At 773 K, the rapid reaction took place based on the different reaction mechanism. Namely, BaZrS3 was formed with a high mole fraction of 0.8 after 1 h heating for α=0.5. At 823 K, the rate of reaction was still more increased, and a mole fraction of 0.92 was obtained for α=2.0 after a very short heating time of 10 min. The maximum BaZrS3 yield attained 0.96 for α=2.0 when the sample was heated at 823 K for 1 h.
