摘要

摘要: 对CuO-Al粉末预制块经不同温度下反应，测试其温度随时间的变化曲线，利用X射线衍射仪对其反应后的试样进行物相分析，得出产生热爆的反应温度及不同温度下的反应产物。结果表明，CuO-Al体系反应随介质温度升高，可分为3个不同阶段，温度小于1 200 K，不发生化学反应；温度为1 200~1 473 K时CuO-Al体系发生部分化学反应，其产物为Cu2O、CuAlO2 及Al2O3；温度高于1 473 K，CuO-Al体系发生化学反应，其产物为Cu和Al2O3，此阶段易出现热爆现象。

Abstract: Chemical reaction in CuO-Al pre-fabricated blocks is controlled at different temperatures. Thermal analysis curves were determined and X-ray diffraction was used to carry out phase analysis of samples after their reactions, whereby the reaction temperature for producing heat explosion and reaction products at different temperatures were obtained. The results indicate that as the medium temperature rises, three different regions of reaction in the CuO-Al system can be classified. When the temperature is less than 1 200 K, there is no chemical reaction; when the temperature is in the range 1 200~1 437 K, a partial chemical reaction takes place whose products are Cu2O, CuAlO2 and Al2O3; when the temperature is over 1 473 K, chemical reaction occurs in the CuO-Al system and the reaction products are Cu and Al2O3. It is in this latter region that thermal explosion is occurs readily.
