The thermal expansion of Y 2 SiO 5 crystals has been measured for the principal crystallographic directions and two orthogonal directions in the (010) plane in the temperature range 25° to 200°C. This monoclinic crystal has strongly anisotropic expansions with coefficients which range from 0.6 × 10 −6 /°C for [100] to 11.4 × 10 −6 /°C for [001]. Third‐order polynomials have been calculated from the expansion curves. Data for the β angle and cell volume as a function of temperature are also given. The thermal expansion of Y 2 SiO 5 crystals is not affected by doping with 5% Tb.
