Effect of Silicon Addition on High-Temperature Solid Particle Erosion-Wear Behaviour of Mullite-SiC Composite Refractories Prepared by Nitriding Reactive

Advances in Materials Science and Engineering, 2014
Solid particle erosion-wear experiments on as-prepared mullite-SiC composite refractories by nitriding reactive sintering were performed at elevated temperatures, using sharp black SiC abrasive particles at an impact speed of 50 m/s and the impact angle ...

Alkali resistance testing methodology and development: Focus on mullite based castables

International Journal of Ceramic Engineering & Science, 2022
Aluminosilicate refractories, which are widely used in alkali‐rich environments, typically have a matrix that is close to mullite in composition. It is the matrix component that is most vulnerable to attack in service.
