Uses include:

High purity magnesium oxide is used in a wide range of industries including agriculture & animal feed, chemical & environmental, food, pharmaceutical & cosmetics, building and construction, mining, fire retardant products, and wastewater treatment.

Hard burned magnesia offers higher density and lower reactivity, making it a more stable ingredient than caustic calcined magnesia across a range of applications.
