Corrosion issues in zinc ingots in hot dilute nitric acid systems
Thread Content
Two reaction vessels were made from 304 stainless steel and 321 stainless steel respectively; the medium used was a dilute nitric acid solution at around 100°C, with which zinc ingots were reacted to produce zinc nitrate. It seems to be just a simple inorganic chemical reaction, but in my reactor, the parts that came into contact with zinc ingots were quickly corroded through. I really can’t figure it out. What do people discuss as the reason?
:I’ve almost forgotten all my chemical knowledge, but you can ask me to look into ways of treating the inner surface of the reactor
:The chemical reactions in the zinc ingot section are intense, affecting the reactor matrix.
It’s more or less like this: just as when water is pumped underwater, the sediment around it also gets carried away. .
The years upstairs – what is the principle behind this?
