Abstract

The initial operation of a Calvet-type calorimeter is reported. The instrument has been designed specifically to study lithium and lithium compound reactions with water at an elevated temperature. Additionally, the calorimeter test section incorporates an environment that resembles actual application conditions. Calibration procedures are explained for three important parts of the instrument, including (1) introduction of the water sample, (2) analysis of the effluent gas, and (3) measurement of the heat of reaction. Ten measurements of the heat of the lithium oxide-water reaction yielded values from 110 to 140 kJ/mol H2O and averaged 124 kJ/mol H2O. The average is in perfect agreement with the theoretical heat value computed utilizing JANAF thermochemical data.
