20 p, 1.1 MB Development of low-melting point molten salts and detection of solid-to-liquid transitions by alternative techniques to DSC / Rodríguez Laguna, María del Rocío (Institut Català de Nanociència i Nanotecnologia) ; Gómez-Romero, Pedro 1959- (Institut Català de Nanociència i Nanotecnologia) ; Sotomayor Torres, Clivia M. (Institut Català de Nanociència i Nanotecnologia) ; Lu, Ming-Chang (National Taiwan University. Department of Mechanical Engineering) ; Chávez Ángel, Emigdio (Institut Català de Nanociència i Nanotecnologia)
The 'Solar salt' (60% NaNO-40% KNO, wt. %) is the most used heat transfer and storage material in high temperature CSP systems. The main drawback is its high melting temperature of 228 °C, which requires extra-energy to keep it in the liquid state and avoid damage to pipes at low temperatures. [...]
