Title
A Study of the Inter - reaction of Sodium Sulfate with Molybdenum Trioxide
정원배Won Bae Chung, 김성수Sung Soo Kim, 강웅기Woong Ki Kang
Abstract
The interaction of sodium sulfate with molybdenum trioxide was studied by differential thermal analysis. It was inferred from this study that sodium sulfate and molybdenum trioxide should react at elevated temperature to yield sulfur trioxide and sodium polymolybdate. The same incipient compound and/or mixture seemed to be formed first at around 660℃ regardless of Na₂SO₄, to MoO₃ratio of mixture during the reaction. When Na₂SO₄to MoO₃molecular ratio of mixture was lower than 1:3, the evaporation of molybdenum trioxide was not observed even at 1000℃.
