Abstract

Powdered mixtures of aluminum with 20 wt % of organic components were subjected to plastic deformation under a pressure of 0.5–4.0 GPa on an anvil-type high-pressure apparatus and then investigated by thermogravimetry and DSC. In deformed mixtures in the T-range of 30–500°C, there was a decrease in mass associated with the decomposition of organic components, while there was an increase in mass associated with the oxidation of aluminum in the T-range of 500–800°C. The mass changes were accompanied by exothermic effects. The enthalpies of exoeffects in the high-temperature range were always higher than in the low-temperature range. The magnitudes of exothermic effects depended on the content of carbon and oxygen in organic molecules; in a series of organic acids, they depended on the pH of acids.

高压塑性变形后铝粉与低分子有机化合物的混合物的热重和DSC研究

摘要

铝粉与20 wt％的有机成分的混合物在铁砧型高压设备上在0.5–4.0 GPa的压力下经历塑性变形，然后通过热重分析和DSC研究。在T-范围为30-500°C的变形混合物中，与有机成分分解相关的质量下降，而在T-范围为500-500范围内，与铝的氧化相关的质量增加。 800℃。质量变化伴随着放热效应。高温范围内的放热焓总是高于低温范围内的。放热效应的大小取决于有机分子中碳和氧的含量。在一系列有机酸中，它们取决于酸的pH值。
