Ba,Sr炭酸鹽の分解ガスに就いて

抄録

Decomposition gases of BaCO₃, SrCO₃, and BaSr(CO₃)₂ were studied by means of a microgas-analyser. Although the major part of the decomposition gas was CO₂, considerable amount of other kinds of gas; CO, HCO₂OCO₂HCO₂ werereleased from the binder, the base metal and by the mutual reaction between gas and metal. The exhaust velocity have serious effect upon the decomposition of carbonates.
Experiments on the decomposition velocity and the dissociation pressure showed that each component carbonate usually decomposes separately even inthe solid solution BaSr(COCO₃)CO₂.
Activation energiesfor the decomposition of BaCOCO₃ and SrCOCO₃ were estimated as about 102 Kcal/mol and 56 Kcal/mol respectively.
