Apparatus developed by the Bureau of Mines for thermal analysis of oil shale was used to determine the thermal properties of shortite. Dissociation of shortite near 470 deg c occurs as an endothermic reaction that could consume significant quantities of heat in the oil-shale retorting process that produces shale oil. The shortite dissociation products undergo other thermal reactions that would not affect the retorting process. These reactions include crystal inversions near 365 deg c and 425 deg c and melting and decomposition endotherms above 500 deg c. Two separate reaction routes for fusion and decomposition of the shortite decomposition products are dictated by the presence or absence of co2 around the sample. Work done in cooperation with the University of Wyoming.
