Conductivity and heat capacity of tranparent ceramics

[frenchero]

Hello,

I want to study transparent alumina and zirconia and I wonder if they have the same conductivity and heat capacity than the dense and opaque materials ? As I can only find datas for the common materials (e.g. dense opaque ones) it would be great!
My point of view is that the difference is mostly in the microstructure and the thermal properties shouldn't be that much upset. Is it correct?

I forgot to notice that I need the evolution of this values with temperature. That's why it is quite hard to find datas.

Thank you for your answers ;)

The conductivity and heat capacity of transparent alumina and zirconia are likely to be quite different from those of dense, opaque materials. This is due to the fact that the two materials have a microstructure that is very different from that of the dense, opaque materials. For example, transparent alumina and zirconia are much more porous than the dense, opaque materials, which affects the way in which they conduct heat and electricity. Additionally, the thermal properties of these materials may be affected by the type of dopants used to make them transparent. As such, it is difficult to provide an exact answer regarding the conductivity and heat capacity of transparent alumina and zirconia without knowing the specific microstructure and dopants used. You may be able to find some data on the conductivity and heat capacity of transparent alumina and zirconia by searching online, but it is likely that you will not be able to find data on the temperature dependence of these properties.
