概要

• 論文の詳細を見る

• The reaction pressure between zinc sulfide and zinc sulfate was measured by the statical method. It was found that the reaction of sulfide with sulfate to yield oxide and SO_2 could proceed through the intermediate phase of basic sulfate. The dependence of the reaction pressure on the temperature can be expressed by the following equations : chemical formula By combining the results of the present investigation with the already existing data, the following thermodynamic values relative to basic zinc sulfate 3ZnO・ZnSO_4 were obtained. chemical formula
