Abstract

In this paper, the reaction beetwen Cr2O3, MgO, Al2O3 was investigated for SPINEL formation in the ternary system. different amount of (1, 2 and 3%) Cr2O3 was studied on the properties and microstructure of SPINEL ULCC REFRACTORY CASTABLEs. In this study SPINEL formation and effect of amount of additive Cr2O3 is under review by X-ray diffraction analysis (XRD) and scanning Electron microscope analysis (SEM) in the temperature 110oC and 1400 and 1600oC on The microstructure and properties of SPINEL refractory casables. results of phase analysis show that small amounts of Cr2O3 lead to complete dissolution of chromia in the alumina (encapsulation), which define absorbed completely and no existed freely. Phase of the Cr+3 enter to SPINEL network and replaced Al+3 ions and Al2O3 and Cr2O3 solid solution will form. Consequently chromia presence, accelerate the process of SPINEL formation and increased mass transfer and density will be.
