Synthetic magnesia is a refractory material with MgO as the main component. Synthetic magnesia is mainly used to produce pre-reacted magnesia chrome bricks. The main component of synthetic magnesia is magnesium oxide, which also contains a part of iron oxide and a small amount of silicon dioxide and calcium oxide. For the analysis of synthetic magnesia, the sample is generally decomposed by the alkali fusion method, and the sample solution is prepared by acid leaching the frit, and then chemical analysis of each component is carried out.
