Study on microstructures and mechanical strength of MgO–C refractories with cobalt‐loaded expanded graphite
Source abstract
Abstract
Abstract Herein, MgO–C refractories were prepared using fused magnesite, aluminum powder, and silicon powder as antioxidants and different kinds of graphite as carbon sources at 1200°C–1600°C. The microstructure and mechanical strength of MgO–C refractories were studied. The results showed that using cobalt‐loaded expanded graphite as partial carbon source, carbon nanotubes (CNTs) were formed in situ in MgO–C refractories at 1200°C, and the CNTs gradually reacted with Si to form SiC fibers over 1400°C. Consequently, the mechanical strength of MgO–C refractories was significantly improved.
