Title Study on the Preparation of Metal/Metal Oxide of Thermite and Its Properties
Abstract
Nowadays, with the development of the society and technology, people have more and more high requirement of Thermite.The lack of Pure Mg/PTFE is becoming increasingly obvious, which shows low energy output, low combustion temperature and the weakness of infrared intensity.By adding other materials to mix with Mg/PTFE in different proportion, achieving the goal that people want to get a better effect of Thermite.This paper mainly studies the preparation and properties of metal/metal oxide’s Thermite.Mainly by preparing five groups of Thermite which are A1+CuO, A1+NiO, A1+SiO2, A1+Fe2O3, Ni+SiO2 in chemical compounding approaches, and then through Scanning Electron Microscope, XRD and other test methods to archive therepresentation of compound medicament's morphology and structure. At last using the different kinds and different proportions of Thermite with Mg/PTFE to prepare the medicine column, then testing the combustion temperature,combustion rate,infrared intensity.The results show that different kind and content of thermite can effectively improve the traditional Mg/PTFE, which can increase the combustion temperature, reduce the burning time, improve the energy released.
