The discussion focuses on identifying solids with varying sound velocities and mass densities at different temperatures, specifically in the context of phononic crystals. The user has found Barium Strontium Titanate (BST) as a suitable material but seeks additional options. A suggestion was made to explore the relationship between bulk modulus and temperature, which may yield further material candidates.
PREREQUISITESResearchers and engineers working in the field of phononic crystals, materials scientists, and anyone involved in the study of sound propagation in solids at varying temperatures.
Welcome to the PF.Mehran said: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
