  Sodium tellurite is a white crystalline solid.

• Chemische Eigenschaften

  White powder. Soluble in water.

• Verwenden

  Disodium Tellurite is an effector towards the thyroid hormone system due to it being of a similar group to selenium. Tellurium accumulates in the thyroid gland and influences the zinc thyroid level. I t is also damaging towards DNA in TK6 human lymphoblastoid cells.

• Verwenden

  Sodium tellurite(IV) acts as an intermediate used in the extraction of the tellurium. It is used to make corrosion-resistant electroplated nickel. It is also used to add a bluish coating to iron, steel and aluminum. It serves as a growth medium for bacteria in microbiology.

• Allgemeine Beschreibung
