“…The thermal and structural changes that occur during the firing of the batches up to 1425 • C were studied by the combination of diffractometric and infrared spectroscopic data at the most remarkable reaction steps. The final product is composed mainly by MgAl 2 O 4 , CaZrO 3 , and Ca 2 SiO 4 phases and the optimal synthesis temperature would be 1425 • C. Tomba Martinez et al [67] have studied the sintering behavior of periclase-doloma refractory mixes. Results showed that the analyzed mixes mainly contain periclase and doloma, with a wide granulometric distribution and different content of minor components (mainly, iron oxides).…”

One of the most important elements of furnaces, boilers and other heating units is the structure (lining), usually made of silica-alumina, basic or special refractories. The basic refractories are materials that are increasingly in demand and whose manufacturing involves necessarily the use of MgO and CaO. In this article, the description and characterization of magnesite (MgCO 3) and dolomite (Mg,Ca(CO 3) 2) and their contribution in industrial ceramics-refractories have been reviewed.

“…However, the application of dolomitic refractory is restricted to the hydration of free CaO [4,8] at room temperature and the low erosion resistance of low basicity slag [1] . In MgO-based refractory, MgO was proved to be less reactive during the manufacture of refractory [5,6,9,10] as well as -2 -during the erosion of refractory. The main erosion focuses on the reaction between slag and CaO [11] .…”

In the current study, the wettability between molten slag and dolomitic refractory materials used in the ladle during steel refining was investigated. The contact angle between molten slag and dolomitic substrate decreased with increasing temperature. The slag with lower basicity spread on the substrate more easily and penetrated deeper into the substrate. The penetration depth of slag into the refractory increased with the extension of holding time. The CaO in the refractory dissolved into slag which was then saturated with CaO. The reaction between slag and substrate resulted in the formation of solid Ca3SiO5, which slowed down the further penetration of slag into the refractory.
