Magnesitean overview ScienceDirect Topics
This chapter discusses properties and use of magnesite –chromite refractories. Lime and magnesia are among the most refractory oxides melting at 2570°C and 2800°C respectively. Magnesite–chrome bricks have very similar properties to chrome–magnesite but are rather less liable to structural spalling.
Magnesite refractory with a high CaO content SpringerLink
Chromite added in amounts of 10 to dolomitic magnesite containing 8.35 CaO by bonding with it completely during firing is an effective stabilizer. An increase in the chromite content of the batch of more than 10 lowers the quality of the refractory. The hydrothermal treatment of the calcined dolomitic magnesite with 10 chromite accelerates the process of hydrating the free CaO and
