#Cronica La termita es una sustancia producto de mezclar aluminio - TopicsExpress

#Cronica La termita es una sustancia producto de mezclar aluminio y un óxido metálico. Al calentarla a altas temperaturas genera una reacción aluminotérmica que a su vez desprende mucho calor. Y bajo determinadas condiciones puede desatar una explosión como la del vídeo. Para lograrlo llenaron un caldero de metal con termita y lo rodearon de bloques de hielo. Después la calentaron a temperaturas de ignición, lo que desembocó en una violenta reacción exotérmica que liberó pequeñas cantidades de hierro fundido. Este descompuso el agua, generando hidrógeno en la reacción, el cual se inflamó y explotó al estar mezclado con el oxígeno del aire.
