What to do with light burnt magnesia powder

Date of release:2018-04-26 Author: Click:

To distinguish the quality of light burnt magnesia powder, first of all, from the color, light burnt commonly known as yellow-white, high temperature. Impurity large color is more important than yellow-dark color. Secondly, according to the chemical composition, lightly burned magnesia powder is generally reduced by 4-5%, over 90% of magnesia, about 1.5% of calcium oxide, and about 1.0 of other iron and silicon respectively.


In addition, if there are conditions, and very concerned about the activity of light burnt magnesium powder, it is necessary to re-test the activity. The higher the content of magnesium, the less impurities, the better the activity. Light-burned magnesia powder is mainly magnesite calcined at low temperature (600-800 degrees), loose texture, high chemical activity, also known as caustic magnesia or bitter soil powder, light yellow color. Because of its high activity, it is easy to react with other raw materials. I haven't heard that it can be directly used for fireworks! Mainly used for calcining spinel, alkali and other refractories
