Thorium Peroxide Nitrate Hydrates

The effect of temperature on peroxide decomposition in a 2M Th(N03)4 solution in 2.2M HNO3 is shown in Fig. 27 the activation energy is 18 2 kcal/mol [2]. 

The peroxide nitrate is stable for at least 2 months on storage in a desiccator [2]. Thermal decomposition yields Th02 at elevated temperature [1].

Thorium tetranitrate hydrates and oxide nitrate hydrates reported to-date are listed in Table 18 with the anhydrous compounds and the presently known peroxide nitrate hydrate and hydroxide nitrate hydrates. The pre-1950 literature is discussed in Thorium 1955,...
