摘要

The thermal stability of cation-ordered perovskite-like layered titanates ANdTiO_4 and A_2Nd_2Ti_3O_(10) (A = Na, K) is studied in the temperature range of 900-1400°C. The structural chemical mechanism of their thermal decomposition is established. A comparative analysis of the thermal stability of compounds with different thicknesses of the perovskite layer and different nature of the alkali cation is performed. The observed thermal behavior is explained from crystal chemical standpoints.
