Sodium selenate (CAS 13410-01-0) is an inorganic selenium salt. Per Ullmann and HSDB it is used as an additive to fertilizers as a selenium micronutrient source, in glass manufacture, and as a laboratory reagent. The anhydrous grade provides a water-soluble selenium source for industrial use.
Frequently Asked Questions
Is sodium selenate the same as selenium?
No. Sodium selenate (CAS 13410-01-0, Na2SeO4) is an inorganic selenium salt, not elemental selenium. It serves as a water-soluble selenium source in industrial applications. Confirm the CAS and assay on the CoA.
What is the difference between sodium selenate and sodium selenite?
They are different selenium salts in different oxidation states: selenate is the SeO4 (Se +6) salt, while selenite is the SeO3 (Se +4) salt. They are not interchangeable and have different CAS numbers, so specify which you need. RawSource supplies the 98% anhydrous selenate grade.
What is sodium selenate used for?
Per Ullmann and HSDB it is used as a selenium-micronutrient additive in fertilizers for selenium-deficient soils, as a selenium source in glass manufacture, and as a laboratory and analytical reagent. The anhydrous grade provides a water-soluble selenium source. RawSource supplies it for these industrial uses.
What is the UN number and HS code for sodium selenate?
It ships under UN 2630 (sodium selenate) and classifies under HS 2842.90. It carries specific DOT shipping requirements, so confirm classification and packaging against the current SDS before transport. RawSource provides the SDS with every order.
What does 98% anhydrous mean for this grade?
It indicates a minimum 98% assay with no water of crystallization, giving a higher selenium content by weight than a hydrated form. The exact assay is confirmed on the CoA for each lot. Specify if your process requires the anhydrous grade.
