Elastic moduli and refractive index of diamond, in the temperature range 300{endash}1600 K, are determined using Brillouin scattering. The elastic moduli decrease by only {approx}8{percent} up to 1600 K, indicating that diamond retains its reputed hardness even at high temperatures. We review the most commonly employed scattering geometries in Brillouin scattering (viz. backscattering, 90{degree} scattering, and platelet geometries), and discuss in detail the experimental errors which must be considered in each case. {copyright} {ital 1998} {ital The American Physical Society}
