Magnesium Oxide Application in Refractories | Martin

Refractory materials maintain physical and chemical stability at high temperatures. Dead-burned magnesium oxide, which is produced in shaft and rotary kilns at temperatures over 1500 o C, has reduced chemical reactivity and therefore is suited to refractory applications.. Magnesium oxide (MgO) has a very high melting point of 2800 degrees C. High melting point, along with resistance to basic …
