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 …

Magnesia Chorme Brick – Rongsheng Refractory
Magnesia chrome spinel refractory bricks, which is rich in magnesia chrome bricks, is a composite of magnesium oxide and chromium oxide, and chromium oxide is a typical neutral oxide. Therefore, magnesia chrome bricks attack alkaline and acid slag,and have strong resistance. Magnesia Chrome Bricks Specification
Production Analysis of MgO Refractory Brick
(4) In the production of MgO refractory bricks, in order to prevent hydration of magnesium oxide, the raw materials are subjected to two calcination treatments. The physical properties of the magnesium oxide lightweight brick thus produced can be further improved.
