Abstract A capacitance micrometer has been developed for the measurement of thermal expansions of small crystals over moderate temperature ranges (approximately 100 K above laboratory temperature). Linear coefficients are obtained to ±0.5×10-6 K-1 and volume coefficients to ±1.5×10-6 K-1. New values are reported for 13 materials, obtained as crystals down to 1 mm in size. For many of these we obtained satisfactory agreement with earlier data, but exceptions are zircon (volume coefficient 6.6±1.6×10-6 K-1, compared with earlier values up to 21×10-6 K-1) and strontium fluoride (volume coefficient 57.9±2.2×10-6 K-1, compared with 42 to 49×10-6 K-1). The new data are combined with values of incompressibility, density and specific heat to obtain new values of Grüneisen's ratio.
