Ceramic nanocomposite is a type of ceramic that incorporates nano size phase to the ceramic matrix to increase ceramic properties and performance further. One method to synthesize ceramic nanocomposite is polymer-derived ceramic polymer-coating method. Polymer-derived ceramic (PDCs) is a polymer material that can transform into ceramic material through pyrolysis process. PDCs have a major flaw when a significant formation of pores is formed during this pyrolysis process. The addition of filler material can be used to prevent this. They will act as ceramic matrix and PDCs as nano phase for ceramic nanocomposite. Polysilazane is one PDCs known for its high temperature performance. On the other hand, yttria-stabilized zirconia is a ceramic commonly used for high temperature applications such as jet-turbine engines. The selection of these two materials is beneficial to each other with yttria-stabilized zirconia can help polysilazane as filler and addition of polysilazane can further enhance the properties and performance of yttria-stabilized zirconia in high temperature application. This research focus discovers polysilazane and yttria-stabilized zirconia ceramic nanocomposite properties in various addition of polysilazane and sintering temperature. These properties are then explained through study literature or characterization of the material. The findings are that the addition of polysilazane and sintering temperature affect the density and hardness of the ceramic, especially at low sintering temperature.
