一般描述
二氧化碲，也称氧化碲（IV）,是一种白色结晶固体，熔点为 1,130 °C ，沸点为1,850 °C。二氧化碲是多种应用中的重要物质，可用作塑性树脂和药物合成的催化剂以及碲基合金中的成分。二氧化碲通常是在氧存在的情况下通过氯化碲（IV）或硫酸碲（IV）在高温下降解生产。
应用
二氧化碲可用于制备金属碲、碲酸和多种碲盐。它还可用于制备Ag2Te纳米颗粒。

TeO(2)-CdF(2)-WO(3) glasses with various compositions and Er(3+) concentrations were prepared by conventional melting method. Their optical properties were studied by measuring the absorption, luminescence spectra and the decay patterns at room temperature. From the optical absorption spectra the Judd-Ofelt parameters
