Description
Tellurium 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. Tellurium dioxide is used as a catalyst for rubber and for metal surface treatment, corrosion resistance, identification of bacteria in vaccines.
