摘要：
The thermogravimetric analysis of potassium disulphate in the ternary sulphate eutectic (Li2SO4-Na2SO4-K2SO4) under various gas atmospheres (N2, SO2-N2, SO2-N2-air) is described. Similar studies on solutions that also contain vanadium or vanadium and niobium, indicated the complex interaction of niobium in the vanadium oxidation-reduction processes and clarified the behaviour of promotors in the catalytic process.
