selenium dioxide
Thread Content
Does any expert know the ratio of nitric acid added during the production process to crude selenium powder regarding selenium dioxide? Please give some advice, thank you!
It is recommended to look up information, conduct experiments, and make comparisons.
What process? Does nitric acid react with selenium powder to produce selenium dioxide? Why not just burn selenium powder directly?
The normal reaction is the high-temperature vaporization of selenium powder in reaction with pure oxygen, but a small amount of nitric acid is added to this reaction process; nitric acid is in gaseous form within the reactor and acts primarily as a catalyst. No, the reaction conversion rate is very low
