Description

technical field [0001] The invention belongs to the field of energy-containing material performance testing technology development, and more specifically relates to an experimental measurement device and measurement method for thermite reaction temperature and burning rate. Background technique [0002] Aluminum is the most abundant metallic element on earth and is regarded as a promising material for energy storage and energy conversion. Thermite reaction refers to the redox reaction process between the mixture of metal aluminum and some metal oxides with lower activity than it. During the combustion process, huge chemical reaction heat will be released rapidly, which makes it have potential scientific research value in the fields of metal welding, energetic explosives, and micro-satellite propellers. At present, domestic experimental research on thermite reaction is still in its infancy, and most of the research focuses on the preparation method, structural characterizati...
