摘要: Provided is an alumina composite ceramic composition which has electrical insulation properties as well as better mechanical strength and thermal conductivity than a typical alumina-based material. Thus, the alumina composite ceramic composition is promising for a material of a substrate or an insulating package of an electronic device. The alumina composite ceramic composition of the present invention may include alumina (Al2O3), zirconia (ZrO2) or yttria-stabilized zirconia as a first additive, and graphene oxide and carbon nanotubes, as a second additive. In this case, in consideration of two aspects of sinterability and electrical resistivity characteristics of the alumina composite ceramic composition, the graphene oxide may be appropriately adjusted to be in the form of a graphene oxide phase and a reduced graphene phase which coexist in the alumina composite ceramic composition.
