Functions

.png For the production of high-purity selenium and other selenium compounds, or organic synthetic drugs, oxidants and catalysts

Used as raw materials for organic compound oxidants, catalysts, chemical reagents, and various inorganic selenium compounds. Also used in copiers, rectifiers, etc.

1, for the production of electrolytic manganese metal

2, for the production of sodium selenite

3, selenium dioxide used as organic compound oxidants, catalysts, chemical reagents, all kinds of inorganic selenium compounds made of raw materials. It is also used as a special reagent for plant alkaloids. It can also be used to precipitate zirconium, hafnium and prepare selenium compounds to react with ammonia to form nitrogen and selenium. In the alcohol solution, it produces ethylammonium selenite [NH? (C? H5) SeO? , With hydrazine to generate nitrogen and black amorphous selenium, with hydroxylamine hydrochloride to produce nitrogen and reddish brown amorphous selenium, with nitric acid to produce selenium acid.

4, selenium dioxide for the system of high-purity selenium and other selenium compounds. Also used in copiers, rectifiers, etc.
