Negative thermal expansion (NTE) material as a compensator is very important for accurately controlling the thermal expansion of materials. Along with the magnitude of the coefficient of thermal expansion, the operating temperature window of the NTE materials is also a major concern. However, only a few of the NTE materials possess both a large operating temperature range and a large thermal expansion coefficient.

Nanocrystalline yttria-stabilized zirconia (ZrO2-8 mol%Y2O3, 8YSZ) was synthesized by a homogeneous precipitation process using urea as the precipitation agent. Zirconia (ZrO2) transparent ceramics samples have been successfully fabricated by a microwave sintering process at low temperature. The technologies of low-temperature microwave sintering and the relationships of the microstructures and properties of the specified samples have been investigated in detail.
