Experimental research on latent heat characteristics of binary mixed molten salt

At present, thermal storage is considered as one of the key technologies to alleviate problem instability and intermittence for renewable energy. Due relatively high latent heat, heat by molten salt a potential technology. Because restriction different thermophysical parameters, application has many technical obstacles. So, it an urgent work find better mixed formula with comprehensive properties. In this paper, we selected halogen salts (NaCl, NaF) alkali (NaOH) prepare binary salts. From results, NaCl-NaOH, NaCl:NaOH=1:9 maximum value 301.2J/g. The initial melting temperature about 200°C. With increase mass ratio NaCl, termination increases firstly then decreases. For NaF-NaOH, NaF:NaOH=1:9 199.5J/g, temperatures are 265°C 380°C, repectively. NaCl-NaOH NaF-NaOH decreased
