6 FAQs about [Sodium sulfate for energy storage]
Is sodium sulfate decahydrate a phase change energy storage material?
In this paper, sodium sulfate decahydrate (SSD) with a phase transition temperature of 32 °C was selected as the phase change energy storage material. However, SSD has the problems of large degree of supercooling, obvious phase stratification, and low thermal conductivity.
Why is sodium sulfate decahydrate a popular inorganic hydrated salt phase change material?
Sodium sulfate decahydrate is a popular inorganic hydrated salt phase change material because of its suitable phase change temperature (32.4 ℃), high latent heat of phase change value (>200 J/g), low price, wide source, safety and non-toxicity.
Is sodium sulfate a good salt hydrate?
For example, sodium sulfate decahydrate, Na 2 SO 4 ·10H 2 O (SSD), has been identified as one of the most promising salt hydrates for building applications due to its low cost (1.60 $/kWh), high energy storage capacity (254 J/g), and moderate melting temperature (32.4 °C) [20, 21].
Can sodium sulfate be stabilized during solid-to-liquid phase transitions?
However, the use of this method to stabilize the undissolved, suspended sodium sulfate (SS) particles during the solid-to-liquid (melting) and liquid-to-solid (freezing) phase transitions of SSD to prevent phase separation has not yet been explored.
What is the melting temperature of sodium sulfate?
The melting temperature of sodium sulfate in the composite materials is around 880 °C and no confinement effect is observed due to the nanoscale diatomite pore size. This indicates that the material should be used at temperatures over 890 °C to maximize the energy density.
Can sodium sulfate be fully dissolved in water?
The remaining anhydrous sodium sulfate (SS) salt cannot be fully dissolved in the water, resulting in a saturated salt solution with undissolved salt particles (Fig. 1 b and f).
