Abstract
Isothermal decomposition of orthorhombic ammonium perchlorate (AP) has been studied as a function of concentration of the dopants, SO 2−4 and PO 3−4 . In either case, the rate of decomposition passes through a maximum as the dopant concentration increases. Activation energy of the decomposition process remains unaltered by doping. The results are interpreted in terms of electron transfer mechanism.
Zusammenfassung
Die isotherme Zersetzung von orthorhombischen Ammoniumperchlorat (AP) wurde in Abhängigkeit von der Konzentration der Dopanten SO 2−4 und PO 3−4 untersucht. In jedem Falle geht die Geschwindigkeit der Zersetzung mit steigender Dopantenkonzentration durch ein Maximum. Die Aktivierungsenergie des Zersetzungsprozesses wird durch dopen nicht verändert. Die Ergebnisse werden auf einem Elektronentransfer-Mechanismus basierend interpretiert.
Резюме
Изучено изотермичес кое разложение орторомбического пе рхлората аммония в зависимости от конце нтрации легирующих д обавок сульфат- и фосфат-ионо в. В каждом случае скорость разложения с увеличением концен трации легирующей добавки п роходит через максимум. Энергия акт ивации процесса разл ожения остается неизменной при легировании. Результаты объяснен ы на основе механизма электронного перено са.
