thermal stability of alkali metal nitrates

Observed reduction temperatures (Tr) for nitrates of the base metals and the noble metals are lower than their Td, i.e., Tr < Td. The solid solutions containing sodium nitrate are thermally unstable and cluster readily to each component species. The rate and extent of annealing increase with increase in free volume of the crystal. hence thermal stability is decreasing. The decomposition temperature of nitrates does not decrease by the coexistence of other nitrates… %%EOF However, in the presence of Pd, the alkali nitrates undergo decomposition at significantly lower temperatures with decomposition starting at ∼80 °C for NaNO3, 130 °C for KNO3, and between 150 and 200 °C for RbNO3and CsNO3. (a) Nitrates … Down the group thermal stability of nitrates increases. The thermal stability of carbonates increases with the increasing basic strength of metal hydroxides on moving down the group.Thus the order is .
