Tellurium Dioxide

Distributor of tellurium dioxide

Description

Tellurium is a rare element; it is rarely found in the elemental state but combined with other metals like gold and silver. The oxide is obtained by adding sulphuric acid to an alkaline solution of tellurium; it remains stable in air and burns with a green flame giving off bioxide. It is an amphoteric substance and therefore can act both as an acid or as a base depending on the solution it is in. It reacts with acids to make tellurium salts and bases to make tellurites. It can be oxidized to telluric acid or tellurates.

Appearance

Tellurium dioxide occurs as a white powder.

Solubility

Tellurium bioxide is highly not soluble in water and soluble in concentrated sulfuric acid.

Uses

Tellurium dioxide is used as a catalyst for rubber and for metal surface treatment.
