Abstract

The phase diagrams of four binary systems (C10H21NH3)2CoCl4−(C16H33NH3)2CoCl4, (C12H25NH3)2CoCl4−(C16H33NH3)2CoCl4, (C10H21NH3)2ZnCl4−(C16H33NH3)2ZnCl4 and (C12H25NH3)2ZnCl4−(C16H33NH3)2ZnCl4 were investigated by means of DSC. These six compounds and their binary mixtures can retain energies between 74 and 115 J/g during solid-state transformations at temperatures between 70 and 105°C, and they are therefore being considered for potential use in solar energy systems.

Zusammenfassung

Mittels DSC wurden die Phasendiagramme der vier binären Systeme (C10H21NH3)2CoCl4−(C16H33NH3)2CoCl4, (C12H25NH3)2CoCl4−(C16H33NH3)2CoCl4, (C10H21NH3)2ZnCl4−(C16H33NH3)2ZnCl4 und (C12H25NH3)2ZnCl4−(C16H33NH3)2ZnCl4 untersucht. Diese sechs Verbindungen und ihre binären Gemische können bei Feststoffumwandlungen zwischen 70 und 105°C Energien zwischen 74 und 115 J/g zurückhalten und wereden deshalb für einen potentiellen Einsatz als Sonnenenergiesysteme in Betracht gezogen.
