High-temperature enthalpy and specific heat of lanthanum and neodymium nickelates
- 1. Moskovskij Khimiko-Tekhnologicheskij Inst., Moscow (USSR)
Description
Nickelates of lanthanum La2NiO4(1) and neodymium Nd2NiO4(2) have been synthesized. The values of enthalpy and the range of 298-923 K are ascertained. The values cp deg (298.15 K) for 1 and 2 are equal to 152±5 and 135±4J/molxK respectively. Phase transition of 2 at 520 deg C is detected and its enthalpy - 1275±410 J/mol is determined
