Heat Capacity of Silver Iodide. I. Experiments on Annealed Samples

Perrott, C. M.; Fletcher, Neville H.


The heat capacity of silver iodide has been measured over the range 50°–400°C using an adiabatic calorimeter, the design of which is discussed. Below about 150°C the behavior of the β form is normal and it transforms to the α form at this temperature with latent heat 1.5 ± 0.1 kcal/mole. If the sample is stoichiometric, the α form has an anomalously high specific heat Cυ, ranging from 18 cal/mole·°C at 150°C to 26 cal/mole·°C at 400°C. If the sample deviates from stoichiometry by as little as 1...[Show more]
