| Abstract: | To develop a new type of carbothermal reduction for the preparation of nitrides, a montmorillonite-polyacrylonitrile intercalation compound was heated inflowing N2 using intercalated polyacrylonitrile as a reducing agent. Nitridation occurred at >1150°C, and β-sialon was obtained, with the formation of β-Sic and AlN. |
