What is Magnesium Oxide

A principal fireproofing ingredient in construction materials, its high thermal conductivity makes it extremely useful in refractories. It is used extensively in soil and groundwater remediation, wastewater treatment, drinking water treatment, air emissions treatment, and waste treatment industries. One of its principal uses is as a component in dry cement production.
