It is widely used in acousto-optic devices, infrared optical materials, electronic applications, and advanced material research. Due to its unique crystal structure and excellent transparency, tellurium dioxide plays a crucial role in precision optics, laser technology, and specialized engineering solutions.
Product Overview
Tellurium dioxide (TeO2) is an oxide of tellurium and exists in two different forms: the yellow orthorhombic mineral tellurite β-TeO2 and the colorless synthetic tetragonal paramorph α-TeO2. It is widely used in scientific research and chemical reactions, especially in the study of paramorph α-TeO2. The chemical properties of TeO2 play a crucial role in various reactions, as it can react with both acids and bases to form different compounds.
Key Features
- Amphoteric: TeO2 can act as either an acid or a base, depending on the solution environment.
- Insoluble in Water: It is insoluble in water but dissolves in strong acids and basic metal hydroxides.
- Oxidizable: Can be further oxidized to form telluric acid or tellurates.
- Two Forms: Exists as yellow orthorhombic β-TeO2 and colorless tetragonal α-TeO2.
Applications
- Chemical Reactions: Used in chemical reactions to prepare tellurates and telluric salts.
- Scientific Research: Important for research, particularly in studies involving the paramorph α-TeO2.
- Materials Science: Used in the production and processing of materials with specific optical properties.
