Use of light magnesia powder

Distinguish the light burned magnesia powder, first of all, from the color, light burn generally called yellow white, high temperature. Secondly, according to chemical composition, burn reduction is generally in 4-5%, Magnesium Oxide 90% above, calcium oxide in 1.5%, and other iron and silicon are good at 1. In addition, if conditions are concerned and care about the activity of light burned magnesia, it is necessary to detect the activity again. The higher the magnesium content, the less impurity the better, the higher the activity is, the better.

Light burned magnesia is mainly calcined magnesite at low temperature (600-800 degrees), loose texture, high chemical activity, also known as caustic Magnesium Oxide or bitter soil powder, the color is light yellow. Because of its high activity, sintering with other raw materials is easy to react. I haven't heard that it can be used directly for fireworks. It is mainly used for calcining spinel, alkali and other refractory materials.
