The Thermal Decomposition of Ammonium Perchlorate : a ' Literature Review

مروری بر رفتار تجزیه حرارتی آمونیوم پرکلرات در حضور نانوکاتالیزورهای اسپینلی(علمی-ترویجی)

Composite solid propellants are the major source of chemical energy in space vehicles and missiles. Composite propellants are composed of crystalline oxidizer particles dispersed in polymeric fuel binder. Ammonium perchlorate (AP) is used as the most common oxidizer and hydroxyl terminated polybutadiene (HTPB) as the fuel binder. The ballistics of a composite propellant can be improved by addin...

مروری بر کاربرد نانو کاتالیست‌های اکسید فلزی برای تجزیه حرارتی آمونیوم پرکلرات (علمی-ترویجی)

In this review, an attempt to collect summarized literature data on catalytic effect of nanosized metal oxides on the thermal decomposition of ammonium perchlorates is made. Several experimental results show nanometal oxides are more effective catalysts as compared to nanosized metals. Nanocatalysts decrease the activation energy and the increase the rate the thermal decomposition of ammonium p...

The Role of Boron in Thermal Decomposition of Ammonium Perchlorate

Simultaneous thermal analysis (STA) method has been applied to study decomposition reactions of AP under a flowing nitrogen atmosphere and static air. Results obtained indicate that a phase transformation occurs prior to the decomposition reaction. Decomposition takes place exothermally in two stages, first stage of decomposition could be suppressed by the controlled heating programme. Addi...

Solvothermal synthesis of copper nanoparticles loaded on multi-wall carbon nanotubes as catalyst for thermal decomposition of ammonium perchlorate

Copper nanoparticles were synthesized on multiwall carbon nanotubes, (Cu)/(MWCNTs), based on solvothermal method. The used reagents include MWCNTs, cupric nitrate trihydrate (Cu (NO3)2.3H2O), diethylene glycol (DEG), diethanol amine. Characterization of Cu/MWCNTS nanoparticles was performed by techniques of Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, X-ray diffraction sp...

In this paper, the effect of nanocatalytic metal-organic framework based on copper metal and bis-tetrazolamine (CuBTA) ligand functionalized with cobalt (II) oxide nanoparticles on the thermal decomposition behavior of ammonium perchlorate (AP), using differential survey calorimetry (DSC) has been reviewed. First, the metal-organic framework (CuBTA) was synthesized from the raw materials of cop...
