Simplified Method for Calculating Elastic Moduli of Ceramic Powder from Compressibility and Debye Temperature Data

A method is presented for calculating the isotropic elastic moduli of ceramic powder from the compressibility and the Debye temperature. Young's and shear moduli of polycrystalline MgO, Al 2 O 3 , BeO, and TiO 2 were computed from compressibility and Debye temperature data by the present method and compared with values determined by the standard resonance method; values agreed within a few percent. An advantage of the present method is its applicability to specimens too small for the resonance method, because both compressibility and Debye temperature can be determined on powder or thin‐film forms.
