“…Combining with the results of XRD patterns in Figure 8, the products with floc morphology might be a layer of silicon nitride film formed on the surface of silicon. 27 By comparing the Figure 9D with B, the addition of Cu increased the quantity of Si 3 N 4 fibers, indicating that Cu facilitated the in-situ growth of Si 3 N 4 fibers. As the nitrided products were mainly α-Si 3 N 4 and the morphology of the products was fibrous, the fibrous silicon nitride can be determined to be α-Si 3 N 4 .…”

With the rapid development of the semiconductor industry and solar photovoltaic industry, a large number of polysilicon wastes from diamond wire cutting are accumulated, which not only pollute the environment, but also cause safety problems due to the ultrafine particle size and high reactivity. The diamond wire cutting polysilicon waste was used to prepare α-Si 3 N 4 by direct nitridation method. This method could not only fully recycle the waste and reduce environmental pollution, but also could reduce the production cost of α-Si 3 N 4. Furthermore, the effects of FeCl 3 , NaCl, and metal Cu on the nitridation of polysilicon waste are investigated in detail, respectively. It is found that FeCl 3 and NaCl are not ideal additives for the preparation of α-Si 3 N 4. However, α-Si 3 N 4-dominated Si 3 N 4 can be obtained via adding 5 wt% Cu after nitridation at 1250°C for 8 hours, and the relative content of α-Si 3 N 4 reaches 92.37%.

Silicon nitride has been researched intensively, largely in response to the challenge to develop internal combustion engines with hot‐zone components made entirely from ceramics. The ceramic engine programs have had only partial success, but this research effort has succeeded in generating a degree of understanding of silicon nitride and of its processing and properties, which in many respects is more advanced than of more widely used technical ceramics. This review examines from the historical standpoint the development of silicon nitride and of its processing into a range of high‐grade ceramic materials. The development of understanding of microstructure–property relationships in the silicon nitride materials is also surveyed. Because silicon nitride has close relationships with the SiAlON group of materials, it is impossible to discuss the one without some reference to the other, and a brief mention of the development of the SiAlONs is included for completeness.
