WHAT IS MOLTEN NITRATE SALT

Solar Energy Storage Potassium Nitrate

It is relevant for the field of energy storage, more precisely for sensible heat storage with nitrate salt melts as heat storage material and heat transfer fluid (HTF). The investigated material Solar Salt is a mixture of sodium nitrate (NaNO3, 60 wt.%) and potassium nitrate (KNO3, 40 wt.%).
