10101-83-4 Usage
Description
Sodium tellurite is a chemical compound with the formula Na2TeO3, which serves as an intermediate in the extraction of the element tellurium. It is obtained from anode slimes and acts as a precursor to tellurium. Sodium tellurite is known for its ability to form black or blue-black coatings on various metal surfaces.
Uses
Used in Metal Coating Industry:
Sodium tellurite is used as a coating agent for providing black or blue-black coatings on metals such as iron, steel, aluminum, and copper. The application of sodium tellurite solutions helps in enhancing the durability, corrosion resistance, and aesthetic appeal of these metals.
Used in Tellurium Extraction:
Sodium tellurite plays a crucial role as an intermediate in the extraction process of the element tellurium. It is obtained from anode slimes, which are by-products formed during the electrolytic refining of copper. The extraction of tellurium from sodium tellurite is essential for various applications in the electronics, solar energy, and metallurgical industries.
Safety Profile
Poison by ingestion, intraperitoneal, and intravenous routes. When heated to decomposition it emits toxic fumes of Te and Na2O. See also TELLURIUM COMPOUNDS.
Check Digit Verification of cas no
The CAS Registry Mumber 10101-83-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,0 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 10101-83:
(7*1)+(6*0)+(5*1)+(4*0)+(3*1)+(2*8)+(1*3)=34
34 % 10 = 4
So 10101-83-4 is a valid CAS Registry Number.
