Title (EN) HYDRATE OF RARE EARTH METAL SULFATE, METHOD FOR PRODUCING SAME, AND CHEMICAL THERMAL STORAGE MATERIAL
(FR) HYDRATE DE SULFATE DE MÉTAL DE TERRES RARES, SON PROCÉDÉ DE PRODUCTION, ET MATÉRIAU DE STOCKAGE THERMIQUE CHIMIQUE
(JA) 希土類金属硫酸塩の水和物、及びその製造方法、並びに化学蓄熱材料
Abstract:
(EN) The problem of the invention is to provide a compound useful as a chemical thermal storage material that is inexpensive, highly safe, has high reproducibility even when reacted repeatedly (high repetition durability), and also makes it possible to proceed reversibly with heat storage and heat release even in a relatively low temperature range. The invention is a hydrate of a rare earth metal sulfate having a characteristic peak at a specific diffraction angle (2θ) in an x-ray diffraction pattern measured using λ=1.5418Å copper radiation through a monochromator.
(FR) L'invention concerne un composé utile comme matériau de stockage thermique chimique peu coûteux, très sûr, présentant une reproductibilité élevée même lorsqu'il réagit de manière répétée (grande capacité de répétition), et permettant également sa mise en œuvre de façon réversible dans le stockage thermique et la libération de chaleur même dans une plage de températures relativement basse. L'invention concerne un hydrate d'un sulfate de métal de terres rares présentant un pic caractéristique à un angle de diffraction spécifique (2θ) dans un diagramme de diffraction des rayons x mesuré à l’aide d’un rayonnement du cuivre λ=1,5418 Å par un monochromateur.
(JA) 本発明の課題は、安価であり、安全性が高く、繰り返し反応を行っても再現性が高く(繰り返し耐久性が高く)、さらに比較的低温領域においても蓄熱と放熱とを可逆的に進行させることができる、化学蓄熱材料として有用な化合物を提供することである。本発明は、モノクロメーターを通したλ=1.5418Åの銅放射線を用いて測定されたX線回折パターンにおいて、特定の回折角(2θ)に特徴的なピークを有する希土類金属硫酸塩の水和物である。
