摘要： 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 (2θ) in an X-ray diffraction pattern, which is measured using a copper radioactive ray of λ=1.5418 Å passed through a monochromator.

摘要： A titanium foil or a titanium sheet is produced by electrodeposition from molten salt using constant current pulse, the method comprising: forming an electrodeposited titanium film on a surface of a cathode electrode made of glassy carbon, graphite, Mo, and Ni, and separating thereafter the electrodeposited titanium film from the cathode electrode by performing one or both of applying an external force to the electrodeposited titanium film and removing the cathode electrode. This enables the electrodeposited titanium film electrodeposited on the cathode electrode to be peeled from the cathode electrode simply and at low cost.
