Corrosion Resistance of Novel Fly Ash–Based Forsterite–Spinel Refractory Ceramics

Original language description

This article aims to investigate the corrosion resistance of novel fly ash–based forsterite–spinel (Mg2SiO4-MgAl2O4) refractory ceramics to various corrosive media in comparison with reactive alumina–based ceramics. Because fly ash is generated worldwide in large quantities as a secondary product from coal-burning power plants, it can be utilized as an inexpensive source of aluminum and silicon oxides. Corrosion resistance to iron, clinker, alumina, and copper was observed by scanning electron microscope with an elemental probe. The influence on the properties after firing was also investigated. Fly ash–based and reactive alumina–based mixtures were designed to contain 10%, 15% and 20% of spinel after firing. Raw material mixtures were sintered at 1550 °C for two hours. Sintered samples were characterized by X-ray diffraction analysis and scanning electron microscopy. The apparent porosity, bulk density, modulus of rupture, refractory and thermo–mechanical properties were also investigated. The experimental results showed that the modulus of rupture, thermal shock resistance and microstructure were improved with increasing amounts of spinel in the fired samples. An analysis of the transition zones between corrosive media and ceramics revealed that all mixtures have good resistance against corrosion to iron, clinker, aluminium and copper.
