Abstract:
We have been investigating molten salts formulated with mixed cations and anions for over 20 years which has led to the discovery of low melting salts with liquidus temperatures below 80 C. The composition of these mixtures is reported to contain lithium, sodium, potassium and/or calcium cations with nitrate/nitrite anions. Physical and chemical properties like viscosity, heat capacity and density are critical parameters to optimize for concentrated solar power generation. As new power generation concepts emerge, the demands on molten salts are increased. We are now investigating the thermal stability of molten salts up to 700 C and optimizing other properties such as heat capacity.
