| Abstract Scope |
Microwave-assisted metallurgy requires use of high-quality refractory materials which should have sufficient chemical stability and microwave transparency at elevated temperatures. Corundum, mullite, forsterite and cordierite are commonly used refractory materials in various metallurgical applications, especially in ironmaking. With relatively low microwave absorptivity, they are candidates deserving attention and exploration. In this study, their application potential in microwave-assisted metallurgy was evaluated from both thermodynamic and experimental perspectives. It was found that their reaction behaviors with FeO, which is a common component in ironmaking feedstocks, differed significantly in the temperature range from 1000 °C to 1400 °C, depending on the temperature and atmosphere. Al₂O₃ exhibited the highest chemical stability, while mullite, forsterite and cordierite showed varying degrees of reaction, forming different compounds. These findings provide valuable insights for selecting proper refractory materials for applications involving microwave energy. |
