Conclusions
-
1.
High-purity lithium perxenonate Li4XeO8· 2H2O was synthesized.
-
2.
The thermal stability of lithium perxenonate was studied by the methods of weight loss of the sample under isothermal conditions, differential thermal and gravimetric analyses.
-
3.
The temperatures of the decomposition of lithium perxenonate depend substantially on the conditions of production and preliminary drying of the preparation.
-
4.
The kinetics of the thermal decomposition of lithium perxenonate were studied, and the activation energy, equal to 55.7 kcal/mole, was determined.
