I need these properties for COMSOL simulation.
Constant pressure heat capacity
Density
Thermal conductivity
Transition temperature between two phases
Melting temperature
Latent heat of fusion.
As a first try, You can add the official properties for Al2O3 (alumina) which are already available in COMSOL.
To do this:
1) Right click on Materials
2) Add Material from Library
3) on the right, search for "al2o3" in the search bar
4) select the Al2O3 which is more suitable for Your simulations (see: attached file)
Please remind that if You measure some of the quantities (or if You find them in literature) it is possible to change the properties of the material selected from library, by entering the Materials subnode on the left of Your COMSOL window.
Best regards,
