Abstract

The effect of dopants, aging, particle size and pre-irradiation on the thermal decomposition of hydrazinium diperchlorate (HP-2) has been investigated. Data on the uptake of $N_2H_6S0_4$ indicate that these impurities are distributed homogenously in HP-2. Anion vacancies have been found to sensitize the decomposition while cation vacancies desensitize. The mechanism of the decomposition has been discussed in terms of the migration of ionic species and electron transfer from $CIO_4^{-}$ ion to $N_2H_{6}^{2+}$ ion.The decomposition is found to desensitize with age. The aging effect is attributed to a decrease in anion vacancy concentration with age. Particle size does not seem to have any effect on the decomposition of HP-2. Pre-irradiation is found to affect the decomposition appreciably only when HP-2 is irradiated for longer durations (> 1 hr), the effect being observed only during the later stages of the decomposition (01 > 0.3).
