High-Temperature Phase-Transition Heat-Accumulating Materials Based on the Li, Na, Ca, Ba‖F, MoO_4 System and Their Properties

摘要

The issues of the physical and chemical analysis of multicomponent systems (MCSs) are considered with the aim to find phase-transition heat-accumulating materials (PHAMs). New salt compositions of eutectic proportions formed by molybdates and fluorides of alkali (Li and Na) and alkaline earth (Ca and Ba) metals, obtained experimentally, are proposed as PHAMs. Their heat of fusion and heat capacity are determined.
