Magnesium powder has been widely used in various industries because it is light weight and extremely high mechanical strength including aeronautics and chemicals. However, magnesium, as a combustible metal, poses serious safety issues such as fires and explosions if it is not managed properly. Especially, magnesium's max adiabatic flame temperature is 3,340℃ and it is impossible to extinguish it by using water, CO2 and Halonagents. The aim of this study is to identify the combustion characteristics of magnesium powder. We carried out a combustion experiment, using 1 kg of magnesium (purity > 99 %, particle < 150 ㎛). The features of the magnesium burning process were scrutinized using infrared thermal image analysis. Also, a field-emission scanning electron microscope (FE-SEM) were used employed to analyze particulate composites and properties. It concludes the significant tendency of magnesium fire and light, combustion carbide's particle characteristics. This study contributes to make better prevention and response manners to magnesium fires, as well as fire investigation measures.
