Effect of the Y 2 O 3 Concentration in YSZ on the Thermophysical Property as a Thermal Shielding Material
Source abstract
Abstract
The effect of the Y 2 O 3 concentration in yttria‐stabilized zirconia (YSZ) on the thermophysical property of porous YSZ was studied. The specific heat capacities ( C p ), the thermal diffusivity (α), the apparent density (ρ) of a 3 mol% Y 2 O 3 /97 mol% ZrO 2 (3YSZ), and an 8 mol% Y 2 O 3 /97 mol% ZrO 2 (8YSZ) were measured. The 8YSZ's C p was lower than that of the 3YSZ. When the YSZs were dense, the 3YSZ's α value by a phonon decreased with an increase in the temperature, whereas that of the 8YSZ was almost constant over a wide temperature range. When the YSZs were porous, the 8YSZ's α value by the phonon was greater than that of the 3YSZ's.
