Tellurite

O2Te (161.8961)

Tellurite is a rare oxide mineral composed of tellurium dioxide (TeO2). It occurs as prismatic to acicular transparent yellow to white orthorhombic crystals. It occurs in the oxidation zone of mineral deposits containing tellurium minerals(Wikipedia). The tellurite ion is TeO32−. A tellurite (compound) is a compound that contains this ion.In slightly acid conditions, we have hydrogen tellurite ion, HTeO3−; with more acidic conditions we have tellurous acid, H2TeO3. Most tellurite compounds can be formed by heating the relevant oxide with tellurium dioxide, e.g., Na2O + TeO2 -> Na2TeO3. Potassium tellurite (K2TeO3) is used together with agar as part of a selective medium for growth of some bacteria (Clauberg medium).
