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.
