Binner, Jon G. P.; Price, Duncan M.; Reading, Mike; Vaidhyanathan, Bala; Hybrid microwave/conventionally heated calorimeter. Review of Scientific Instruments 76 (2005) 064902-1-4
The design and construction of a calorimeter in which the specimen may be heated by microwave radiation and/or hot air is described. The apparatus was used to examine the effect of microwave radiation on the melting of benzil (89°C) and the solid-state phase transition of silver iodide (147°C). Reproducibility of transition temperature determinations were within ±1°C. No changes were observed for benzil but silver iodide exhibited an apparent reduction in transition temperature to around 120°C in the presence of microwaves, which increased with the level of microwave irradiation.
