Magnesium Oxide with Low Fe2O3 and high LOI, color is white, reactivity is high, it is more suitable for magnesium board production. Below are reasons why:
Fe2O3 content: Iron oxide is a common impurity in magnesium oxide. The presence of Fe2O3 can affect the color and reactivity of magnesium oxide. In this case, you mentioned that the magnesium oxide has low Fe2O3 content, which is desirable. A low Fe2O3 content ensures that the magnesium oxide remains white in color. Iron oxide can impart a yellow or brown tint to the material, which is undesirable for magnesium board production.
LOI: LOI refers to the loss on ignition, which is the weight loss experienced by a material when heated to high temperatures. In the case of magnesium oxide, the LOI typically represents the loss of water and/or carbon dioxide. High LOI indicates that the magnesium oxide contains a significant amount of water or other volatile components. This is favorable for magnesium board production because the release of these volatile components during the manufacturing process can contribute to the formation of pores and help improve the board's porosity and strength.
Reactivity: Magnesium oxide with high reactivity is desirable for magnesium board production. High reactivity implies that the magnesium oxide readily reacts with other components, such as binders and fillers, during the board manufacturing process. This reactivity promotes strong bonding between the particles, resulting in a more durable and structurally sound board.
