轻烧镁粉一般做什么用 What is the general use of light burning magnesium powder

    辨别轻烧镁粉好坏,首先从颜色，轻烧的一般称黄白色，温度高.杂质大颜色偏重于黄深色。其次，根据化学成分，灼减一般在4-5% ，氧化镁90%以上，氧化钙在1.5%一下，其他铁，硅好的分别都在1.0一下。另外若有条件的话，并且很在意轻烧镁粉的活性，那就需要再检测活性。镁含量越高，杂质越少越好，活性越高越好。轻烧镁粉主要是菱镁矿低温煅烧（600-800度），质地疏松，化学活性高，也称苛性氧化镁或苦土粉，颜色淡黄。因其活性大，和其他原料配比烧结很容易反应。没有听说可以直接用于烟火！主要用于煅烧尖晶石，碱性等耐火材料。

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.
