설명

일반 설명

Tellurium dioxide, also known as tellurium(IV) oxide, is a white, crystalline solid with a melting point of 1,130 °C and a boiling point of 1,850 °C. Tellurium dioxide is an important material in a number of applications, including as a catalyst in the synthesis of plastics resins, and pharmaceuticals, and as a component in tellurium-based alloys. Tellurium dioxide is typically made at high temperatures either by decomposition of tellurium(IV) chloride or tellurium(IV) sulfate in the presence of oxygen.

애플리케이션

Tellurium dioxide is used to prepare tellurium metal, telluric acid, and many tellurium salts. It may also be used in the preparation of Ag2Te nanoparticles.
