Light burned powder and magnesium oxide

Light burned powder is the product of light burned natural magnesite or brucite at about 900 ℃. It's commonly known as light baking powder. The main chemical composition is magnesium oxide. Generally speaking, magnesium oxide refers to the chemical production of magnesium oxide. Magnesium carbonate or magnesium hydroxide, which is produced by chemical method with magnesium containing raw materials, is the magnesium oxide obtained by calcination. Therefore, the so-called magnesium oxide generally has significant differences in purity, granularity, activity and other indicators with light burned powder.
