Introduction | Samarium bromide hexahydrate is a yellow deliquescent crystal. Samarium bromide hexahydrate decomposes into samarium bromide and bromine after losing water. Preparation method: Soluble samarium oxide in ammonium bromide or hydrobromic acid solution, evaporated and concentrated. | |
Application example | CN201610426075.5 discloses a low-loss and high-efficiency solar heating system, which includes: a solar energy collection system, which gathers scattered solar energy and converts it into heat energy; Energy storage system, which forms an energy storage circulation pipeline with the solar energy collection system, and the energy storage medium absorbs heat energy; heating system, which has a thermal storage tank and heat dissipation equipment, the energy storage circulation pipeline passes through the thermal storage box to heat the heating medium in the thermal storage box; the medium and low temperature power generation system has a low boiling point medium, and the low boiling point medium absorbs the heat of the energy storage medium, the heating medium includes 30-50wt% lanthanum bromide, 20-40wt% samarium bromide hexahydrate, 20-40wt% cerium bromide, 0.3-0.8wt% polyethylene glycol and 0.2-0.5wt% mannitol. The design of the invention is reasonable, the energy-saving effect is obvious, the efficiency is high, and the design of the insulation layer can ensure the safe operation of the system in cold winter and the antifreeze under the condition of accidental power failure. | |
