Abstract

A new nanothermite system, composed of titanium and tungsten trioxide is reported. Initial investigations show that it has low-average sensitivity to mechanical stimuli (friction, impact), but that its sensitivity to laser irradiation can be controlled in a moderately wide range. The combustion of this nanothermite system takes place at a very high apparent temperature (> 3695 K) and it follows the key predictions of the established reactive sintering mechanism, as supported by SEM-EDS and XRD analyses.

Ti/WO3,一种特殊用途的纳米热敏电阻:实验研究
本报告介绍了一种由钛和三氧化钨组成的新型纳米温石棉系统。初步研究表明,它对机械刺激(摩擦、撞击)的平均灵敏度较低,但对激光照射的灵敏度可控制在中等范围内。这种纳米热敏体系的燃烧发生在很高的表观温度下(> 3695 K),它遵循了已确立的反应烧结机制的主要预测,并得到了 SEM-EDS 和 XRD 分析的支持。
