Preparation and characterization of SiAlON matrix composites reinforced with combustion synthesis rod-like SiAlON particles

Effects of alumina sources on the microstructure and properties of nitrided Al2O3-C refractories

“…Industrial alumina contains γ-Al 2 O 3 , which transforms into α-Al 2 O 3 through an exothermic process. The exothermic phase transformation promoted the reduction of Al 2 O 3 and β-Sialon followed formulas (13) and (14), and resulted in weight loss.…”

“…This material has attracted considerable attention due to its superior properties at elevated temperatures [11]. Because of the excellent mechanical and thermal properties as well as the corrosion resistance of β-Sialon, the original properties of Al 2 O 3 -C refractories are not degraded by the formation of β-Sialon [12][13][14][15]. Furthermore, β-Sialon can form a thin layer of mullite during early oxidation, which can protect the carbon and β-Sialon from further oxidation [10].…”

Abrasive wear behavior of SiCp–Sialon composite refractories

“…The wear resistance of composites can be improved by increasing the fracture toughness [8,9]. At present, various methods, such as a reaction-bonded process, [10][11][12] improving sintering methods, [13,14] introducing the second phase, [15][16][17] microstructure design, [18,19] adding sintering additives [20][21][22]. have been proposed to reinforce the fracture toughness of ceramics.…”

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

“…However, under more severe conditions, composites with higher -sialon content showed better wear properties [11][12][13]. Chen et al [14][15][16][17] have proposed thatsialon could be easily prepared by high-temperature combustion syntheses, which were suitable for use as reinforcing agent in composites. It was found that with increasingsialon content in the composites, there was a monotonic increase in both bending strength and fracture toughness.…”
