Determining Reactivity of Magnesia
In the industrial minerals market, Magnesium Oxide (MgO) is rarely a "one-size-fits-all" product. Depending on the calcination process and the raw material source, the properties of MgO can vary drastically. For procurement managers in industries ranging from refractory manufacturing to animal feed and construction materials, understanding the reactivity of magnesia is not just a technical detail—it is the deciding factor in product performance. At YFTD , we often encounter clients asking how to distinguish high-quality active magnesia from standard grades. Here, we break down the key methods for determining reactivity and why it matters for your business. What is Magnesia Reactivity? Reactivity, often referred to as "activity," describes the chemical activity level of magnesium oxide under specific conditions. It is primarily determined by the calcination temperature. Light Burned Magnesia (Active MgO): Calcined at lower temperatures (800°C–900°C), this type r...
