  • Hydrate of Rare Earth Metal Sulfate, Method for Producing Same, and Chemical Thermal Storage Material
    Publication number: 20190002302
    Abstract: An object of the present invention is to provide an inexpensive and highly safe compound useful as a chemical heat storage material that ensures high reproducibility even in repeated reactions (having high repetition durability), and is capable of reversibly advancing heat storage and heat dissipation even in a relatively low temperature range. The present invention is a hydrate of a rare earth metal sulfate having characteristic peaks at specific diffraction angles (2?) in an X-ray diffraction pattern, which is measured using a copper radioactive ray of ?=1.5418 ? passed through a monochromator.
