Abstract
The heat capacity of LaMgAl11O19 with a magnetoplumbite structure was measured in the temperature range of 7–1865 K using relaxation, adiabatic and differential scanning calorimetries. Obtained temperature dependences of the heat capacity are consistent based on adiabatic calorimetry data. Thermodynamic functions (entropy, enthalpy change, reduced Gibbs energy) in the range 0–1865 K are calculated from fitted values. Thermal expansion in the range of 300-1200 K was studied by high-temperature X-ray diffraction and the coefficient of thermal expansion of LaMgAl11O19 was calculated.
