Direct heating is used here; inside the container, NaCl, MgCl, KCl, and BaCl are mixed in certain proportions and melted to serve as a heat carrier. The temperature of this heat carrier is 500 degrees. What material should be used for the container? As a supplementary point, the container is under negative pressure, which facilitates the timely removal of the gases generated and prevents secondary reactions; therefore, strict pressure control requirements are not necessary. Mainly, how to address the corrosion caused by chloride ions at high temperatures?
16MnR is a common low-alloy steel, specifically designed for use in boilers and pressure vessels; it is a frequently used material in such applications. I think 16MnR is quite effective
