应用
It is used as an acousto-optic material and a conditional glass former. The glasses of tellurium oxide have high refractive indices. Owing to the transmission into mid-infrared part of the electromagnetic spectrum, tellurium oxide is of technological interest for optical waveguides. It is also employed in optical fibre amplification. 备注

产品说明 一般描述 Tellurium dioxide (TeO2) is a ceramic material that can be used as a semiconducting oxide. It has a wide band gap and high mobility as determined by density functional theory (DFT) calculations. In bulk quantity, it exists in two polymorphs which include tetragonal α-TeO2 and orthorhombic β-TeO2. 应用 TeO2 can be potentially used in medical imaging and industrial monitoring processes. 包装 50, 250 g in poly bottle 基本信息 | 线性分子式 | TeO2 | | 分子量 | 159.60 | | EC 号 | 231-193-1 | | MDL编号 | MFCD00011263 | | PubChem化学物质编号 | 57653113 | | NACRES | NA.23 |
