DOI: 10.1016/j.jeurceramsoc.2020.07.035
Abstract: Abstract Calcium aluminate cement-bonded Al2O3-SiC-C castables are widely used in practice due to sufficient initial strength and operability. However, a high amount of cement leads to deteriorated high-temperature properties due to the formation of low-melting-point… read more here.
