Magnesite bricks, Magnesite (MgCo3) is used to produce magnesia refractories, also known as Refractory Magnesite Bricks. Magnesia fired at 16000°C is known as DBM or Dead Burned Magnesite which is essential in Production of magnesia based Refractory. The refractoriness of Magnesite bricks is about 18000°C. This is dependent on the Melting point of the bond. The RUL ranges from 14500°C to 17200°C. Spalling Resistance is poor for some grades and good for others. One reason for the poor Spalling resistance is a high coefficient of thermal expansion. Magnisite has the Highest thermal expansion coefficient among all Refractories. Spalling resistance is also dependent on the porosity.
