摘要：

The heat capacity and enthalpy of lutetium monosiliNide are measured for the first time in the temperature ranges 68.56-298.21 and 465-2191 K, respectively. The standard values and temperature dependences of the heat capacity, entropy, Gibbs energy, and enthalpy of the silicide are calculated in a wide temperature range. The temperature, enthalpy, and entropy of melting are determined.
