%X The reactions of lanthanum metal, La2O3, La(OH)3, La(NO3)3.6H2O, La2(CO3)3.3H2O, LaCl3 and LaCl3.7H2O with molten K2S2O7 were studied. The metal reacted with K2S2O7 to produce La2(SO4)3, K2SO4 and SO2. Lanthanum(III) oxide was converted into La2(SO4)3, as were La(OH)3, La(NO3)3.6H2O, La2(CO3)3.3H2O, LaCl3 and LaCl3.7H2O but with the evolution of H2O, NO2 + O2 + H2O, CO2 + H2O, Cl2 + SO2 + S and Cl2 + SO2 + H2O + HCl respectively. K2S2O7 was converted into K2SO4 in the reactions. Reaction pathways have been suggested to explain the final products. The temperatures and stoichiometries of the reactions have been established.
