摘要： The microscopic morphologies of Bi30Ga70 immiscible alloy particles were investigated. Monosized microparticles with similar core-shell structures were fabricated for the first time by one step using the Pulsated Orifice Ejection Method. The EDS revels that the core and the shell consist of a Ga-rich phase (>90 at. %) and a Bi-rich phase (>80 at. %), respectively. The DSC testing at different temperatures is performed. Core-shell microstructures as well as endothermic peaks and exothermic peaks are observed after heating-cooling cycles when the working temperature is below the temperature of spinodal line, indicating good thermal stability after phase transformation. The thermal energy storage was preliminary tested, which is a good attempt for thermal energy storage. It is likely to use core-shell structures as microencapsulated phase change materials. ?
