MAGOX® is America’s original magnesium oxide (MgO), mined
and calcined from the only domestic source of magnesia ore in the United States. Its
quality surpasses that of other MgO sources around the world due in part to the precision employed during the calcining process.
How production process can affect MgO quality
MAGOX® is calcined under exacting conditions in a
computerized multiple-hearth furnace, guaranteeing uniform
temperature and yielding high quality, consistent MgO. Premier is the only
producer in North America using this technology. Most other sources of MgO are typically made
in a rotary kiln, with only a single burner. Material temperature is thus more
difficult to control resulting in inconsistencies that reduce reactivity, and
end up costing the user more.
Reactivity vs. MgO Content
MgO content is important, but if the material is
overheated during calcining, the higher MgO can actually lower
performance. So although % MgO matters,
it is not solely indicative of the quality of the product. “Reactivity” on the
other hand, is what plays a bigger role in the effectiveness in an application.
Reactivity is a measure of how quickly MgO reacts with acid. Lower reactivity
means more MgO passes through the system without having much effect. This can
increase both material demand and cost. In addition, both solubility and
bio-availability of MgO can also be influenced by temperature. In certain
applications, such as in the agriculture industry, solubility and
bio-availability are essential factors for plant and animal magnesium uptake.
In summary, understanding the process by which an MgO source
is calcined, is important for understanding the quality and therefore effectiveness
in an application. MAGOX has been used
successfully across dozens of applications in a wide-range of industries.
