“…The remarkable properties of Sialon combined with the high hardness of TiB 2 have been reported in previous investigations. TiB 2 particles are contained in Si 3 N 4 or Sialon matrix, and the density of the material is close to the theoretical value compared to Si 3 N 4 alone, which has high hardness and reasonable fracture toughness 20 . TiN, TiB 2 , and Sialon are all high performance materials, which can be utilized as the interface binder of cBN.…”

Polycrystalline cubic boron nitride (PcBN) composites were synthesized in situ with TiB2, TiN, and Sialon as binders under ultrahigh temperature (1550°C) and high pressure (5.5 GPa). X‐ray diffractometry, universal testing machine, field emission scanning electron microscopy, and transmission electron microscopy were used to study the effect of Sialon content (0%, 20%, 40%, 60%, and 80% by mass of binder) on the phase composition, microstructure, and mechanical properties of PcBN composites. The results show that the main phases in the system are lamellar TiN, needle‐rodlike TiB2, and irregular long‐rodlike Sialon. Some TiB2 grows along the (1 0 −1 0) face, and Sialon grows along the (0 0 0 1) face. The density and mechanical properties of the sintered product are significantly improved due to the formation of Sialon. When the content of Sialon is 60%, the binder is uniformly distributed, the cBN interface is well bonded, and the density is the highest. At this time, the strength reaches the maximum 34.57 GPa, the fracture toughness is 6.82 MPa m1/2, and the flexural strength reaches the maximum 870.79 MPa. On the whole, cBN composites have excellent prospects for future applications in cutting inserts due to their excellent mechanical properties.

“…For example, Guo et al [ 13 ], using α-Si 3 N 4 , AlN, and Al 2 O 3 as the raw materials, synthesized SiAlON ceramics by spark plasma sintering at 1600–1750 °C under vacuum atmosphere. Li et al [ 14 ] fabricated β-SiAlON/hexagonal boron nitride (h-BN) nanocomposite by a precursor infiltration and pyrolysis (PIP) route using Si 3 N 4 , Al 2 O 3 , and AlN as the starting materials. Tian et al [ 15 ] fabricated β-SiAlON powders under nitrogen atmosphere using Al, Si, α-Al 2 O 3 , and trace Y 2 O 3 powders as starting materials, and studied the effect of Y 2 O 3 powder on the oxidation resistance of β-SiAlON.…”

Al2O3-bonded SiAlON ceramic with self-coating was prepared using aluminum dross and silicon solid waste as starting materials under ambient air conditions. The changes in phase, microstructure, and physical properties of the ceramic with temperature were analyzed and the formation mechanism of the SiAlON phase was elucidated. The results showed that higher temperature was more suitable for the preparation of SiAlON ceramics. As the temperature increased from 1400 to 1600 °C, the main phases in the ceramic transformed from mullite, Al2O3, and SiAlON to Al2O3 and SiAlON. An Al2O3-rich layer spontaneously coated the surface of the porous ceramic as Al melted and oxidized at high temperature. The thickness of this layer decreased as the temperature increased. The presence of Al2O3-rich coating layer impeded air flow, allowing nitriding of Si and Al, and the formation of the SiAlON phase in ambient air conditions. This study not only presents a strategy to successfully recycle aluminum dross and silicon solid waste but also offers a straightforward approach to preparing SiAlON material in air atmosphere.
