“…Nextgeneration solar power conversion systems in CSP applications are targeting high-temperature, advanced fluids to operate in the range of 600-800°C, which are temperatures that exceed the range of nitrate stability. Chloride molten salts are promising candidates, but are corrosive to common alloys used in vessels, heat exchangers, and piping at these elevated temperatures [4]. Containment material degradation is a major concern to meet commercial viability of next generation CSP plants [5].…”

“…Introduction of oxygen and moisture have deleterious effects as discussed earlier. Studies will be discussed contrasting additions of oxygen [15,16], wet and dry O2 streams [20,21], and use of chlorine in situ above the salt [17].…”

“…The influence of moisture results in a twofold effect: introduction of oxygen for worsening corrosion and evolving HCl, which will act to exacerbate corrosion in the head space. During experiments with chloride salts, an observed continually evolved fuming was observed causing further corrosion of metal near the crucible where tests took place [21]. The partial pressure of water during tests was estimated to be 0.1-1% and half of alloys tested disintegrated after six days of exposure under these conditions (900°C, NaClMgCl 2 ) [21].…”
