Distinguish the quality of lightly burned magnesium powder, first of all from the color, lightly burned is generally called yellow-white, high temperature. The color of large impurities is more important than the dark yellow. Secondly, according to the chemical composition, the burning reduction is generally 4-5%, the magnesium oxide is more than 90%, the calcium oxide is less than 1.5%, and the other iron and silicon are better than 1.0. In addition, if there are conditions, and you are very concerned about the activity of lightly burned magnesium powder, you need to test the activity again. The higher the magnesium content, the less the impurities, the better, and the higher the activity, the better. Light-burned magnesium powder is mainly low-temperature calcined magnesite (600-800 degrees), with loose texture and high chemical activity. Because of its high activity, it is easy to react when sintered with other raw materials. I haven't heard that it can be used directly for fireworks! Mainly used for calcining spinel, alkali and other refractories.
