纳米LaCoO3对RDX基混合炸药的热分解特性和感度的影响
The Effect of Nano-LaCoO3 on the Thermal Decomposition and Sensitivity of RDX Explosive Mixture
【摘要】 用DSC和DTA研究了LaCoO3对含AP的RDX基混合炸药热分解特性的影响。结果表明,纳米LaCoO3对含有AP的RDX基爆炸混合物的热分解具有一定的催化作用;纳米LaCoO3使RDX基混合炸药的撞击感度和热感度降低,摩擦感度增大。
【Abstract】 The effect of nano-LaCoO3 on the thermal decomposition characteristics of RDX explosive mixture containing ammonium perchlorate was investigated by DSC and DTA. The results show that nano-LaCoO3 has catalytic activities to the thermal decomposition characteristics of RDX explosive mixture. The results of sensitivity tests show that the nano-LaCoO3 makes the impact sensitivity and thermal sensitivity of these explosive mixture decrease and the friction sensitivity of the mixture increase.
