Tellurium dioxide (TeO2) is a solid oxide of tellurium. It is encountered in two different forms, the yellow orthorhombic mineral tellurite, β-TeO2, and the synthetic, colourless tetragonal (paratellurite), α-TeO2.
T 1253 (OTTO) Tellurium oxide, 99.99% Cas 7446-07-3 - used to prepare tellurium metal, telluric acid, and many tellurium salts. T 1253 (OTTO) Tellurium oxide, 99.99% Cas 7446-07-3 - used in the preparation of Ag2Te nanoparticles. T 1253 (OTTO) Tellurium oxide, 99.99% Cas 7446-07-3 used to make glasses with special properties. It is useful in optical waveguides and optical fiber amplification.
