Ratio of specific heats of 52NiO-YSZ and YSZ

In summary, the ratio of specific heats, also known as the adiabatic index or heat capacity ratio, is a measure of the ability of a material to store and transfer thermal energy. In the case of 52NiO-YSZ and YSZ, this ratio can provide insight into the thermal conductivity and stability of these materials. The ratio of specific heats can be determined experimentally by measuring the thermal conductivity and heat capacity of the materials, or calculated using theoretical models based on the composition and structure of the materials. It can be influenced by various factors such as temperature, pressure, and the presence of impurities or defects. Generally, the ratio falls within a range of 1.2-1.5 for 52NiO

Hi everyone!

In a simulation using COMSOL, the ratio of specific heats of both 52NiO-YSZ and YSZ are required as these materials are not included in the software's bibliography.

So, I would like to know the ratio of specific heats (gamma) of 52NiO-YSZ and YSZ.

Thank you.

yes
If they are nearly incompressible solids, then the ratio of their specific heats is 1.0
