文摘The thermal diffusivities of new PbB4O7, crystal determined by the optical beam deflection (OBD) technique at room temperature are provided. The experimental results indicate that the thermal diffusivities of this crystal in the orientations of the three main axes are anisotropic; there is an elliptical distribution of the thermal diffusivities versus the detecting angle in the X-Z plane for the 0° Y-cut plate. This result agrees with the theoretical estimation.
