Abstract
A method of fabricating an article for magnetic heat exchange is provided. The method comprises mixing a binder comprising a poly (alkylene carbonate) and powder comprising a magnetocalorically active phase with a NaZn13-type crystal structure to produce a brown body or powder comprising elements in amounts suitable to produce a magnetocalorically active phase with a NaZn13-type crystal structure, removing the binder from the brown body to produce a green body, and sintering the green body to produce an article for magnetic heat exchange.
