Abstract

In this work, we present the design of a photoacoustic system to study the photoacoustic phenomena that can be used for the experimental determination of the thermal diffusivity of solids. The photoacoustic system with an open photoacoustic cell studies the photoacoustic signal of Fe₂Mo pellets that have been produced from powder by gas-solid reduction. we use the Rosencwaig and Gersho (RG) model to determine the thermal diffusivity of Fe₂ Mo. The thermal diffusivity of the Fe₂Mo calculated is 0.0147 cm²/s ± 0.0001.
