Abstract

The effect of quasi-millimetre-wave (24 GHz microwave) heating on creep deformation was investigated on partially-stabilised zirconia through tensile testing at temperatures from 1100 to 1350 °C over stresses from 3 to 10 MPa. The specimens were fabricated by sintering the 3 mol% of yttria stabilised ZrO₂ (3YSZ) powder dispersed with SiO₂, SiO₂/SnO₂ or SiO₂/TiO₂ at 1600 °C. In tensile test using the quasi-millimetre wave heating, strain rates of SiO₂ dispersed 3YSZ were similar to that with a conventional furnace heating. The 3YSZ sample containing the TiO₂ addition exhibited a different strain rate when heated by millimeter-wave irradiation as against conventional furnace heating, it is proposed that this difference can be explained due to TiO₂ having a high-dielectric constant resulting in a non-thermal effect when subjected to quasi-millimeter wavelength radiation.
