Full Dense SiCN Ceramics Derived from Polysilazane

Abstract:

Full dense silicon carbonitride (SiCN) ceramics have been prepared successfully by thermally induced ceramisation of polysilazane precursor at 1000°C, and subsequently annealing at 1200°C. The density and the hardness of the obtained ceramics were about 2.61g/cm³ and 13GPa at the pyrolysis temperature of 1000°C, respectively. The density and hardness have a slight change with the increasing annealing temperature. This meas that the ceramics pyrolyzed at 1000°C were stable.
