Abstract: MgAl2O4 is an important refractory. In addition to utilizing its inherent properties, the in-situ formation of MgAl2O4 at high temperatures, including secondary spinelization, is an important means to regulate the microstructure and service performance for refractories. Its expansion effect can offset the shrinkage caused by sintering, which can improve the corrosion resistance of liner such as Al2O3-MgO castables, low-carbon MgO-C refractories, and Al2O3-MgO-C refractories. Additionally, this effect can seriously affect the reliability of functional refractories. This paper firstly introduces the in-situ formation mechanism of MgAl2O4 and focuses on the formation process by gas phase and the phenomenon of secon-dary spinelization. Based on the composition, particle size, atmosphere, temperature and products morphology, the factors for in-situ MgAl2O4 formation and their influence on the microstructure and properties of materials are further systematically summarized in Al2O3-MgO-MgAl2O4 system and carbon-containing system, respectively. Some ways for regulating microstructure and service performance of refractories and several weak contents of current research are also proposed. This paper will provide an important reference for the preparation of refractories with high corrosion resistance and high reliability.
