Solids with different sound velocity at diffrent tempratures

[Mehran]

i work on phononic crystals and i want to find solids with diffrent sound velocities and mass density in diffrent temprature
i can just find BST
but i need more matherials
please help me my friends
best regards

Welcome to the PF.

I did a google search on Bulk Modulus Versus Temperature, and got lots of good hits. Maybe start there?
