1. Only in basic conditions is tellurite formed. 2. Sodium tellurite ( Na 2 TeO 3 ) is lethal in amounts of around 2 grams. 3. Natural tellurite and tellurate minerals also occur, formed by oxidation of tellurides near the Earth's surface. 4. "' Sodium tellurite "'is an inorganic tellurium compound with formula Na 2 TeO 3. 5. The related conjugate base is well known in the form of several salts such as potassium acid tellurite , KHTeO 3. 6. Several types of fibers have been successfully tested : non-zero dispersion-shifted fibers, chalcogenide fibers or tellurite fibers. 7. The co-presence of TerC and TerE but not TerF correlates with tellurite resistance when several hundred bacterial strains were assayed. 8. It is also associated with native tellurium, tellurite , native gold, pyrite, rodalquilarite, mackayite, sonoraite, cuzticite and eztlite. 9. Most tellurite compounds can be formed by heating the relevant oxide with tellurium dioxide, e . g ., Na 2 O + TeO 2 ? 10. Potassium tellurite ( K 2 TeO 3 ) is used together with agar as part of a selective medium for growth of some bacteria ( Clauberg medium ).
