Sealing materials resistant to molten sodium metal
Thread Content
I recently encountered a difficult problem: the medium is molten sodium metal, as it corrodes the commonly used PTFE material. After searching online, I couldn’t find any sealing material that can resist corrosion by sodium metal. I was wondering if any expert could advise me on what sealing materials (such as rubber or plastic) can resist corrosion by molten sodium metal Thank you!
Sealing rings made of flexible graphite can be used. 300°C is still achievable.
Niobium, metal plate – that should work. It seems it cannot be used at too high temperatures
Thank you, but the graphite material tends to shed debris, and the customer will not accept it. Are there any special rubber or plastic sealing materials?
