FAQ

What are the physical and chemical properties of Zinc telluride (CAS: 1315-11-3)?

Zinc telluride (ZnTe, CAS: 1315-11-3) is a direct-bandgap semiconductor with a cubic zinc-blende crystal structure. Its molecular weight is approximately 248.14 g/mol. It is insoluble in water but soluble in strong acids. Chemically, it is stable at room temperature but can react with halogens and strong oxidizers.

How is zinc telluride (CAS: 1315-11-3) typically synthesized?

Zinc telluride is typically synthesized by the solid-state reaction method, where zinc oxide (ZnO) and tellurium (Te) are heated to temperatures around 900°C. Alternatively, it can be produced using chemical vapor deposition (CVD) or metal organic chemical vapor deposition (MOCVD) techniques, which provide better control over crystal quality and purity.

What industries use zinc telluride (CAS: 1315-11-3)?

Zinc telluride (ZnTe, CAS: 1315-11-3) is primarily used in semiconductor applications, including photovoltaic cells, infrared optical devices, and sensors. It is also used in the production of phosphors and as a dopant in other semiconductor materials. Additionally, it has applications in the pharmaceutical industry for certain compounds and in the polymer industry for specific additives.

What precautions should be taken when handling zinc telluride (CAS: 1315-11-3)?

When handling zinc telluride (ZnTe, CAS: 1315-11-3), it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or fume hood. Spills should be cleaned up immediately using appropriate absorbent materials, and the area should be thoroughly cleaned. Always refer to the Safety Data Sheet (SDS) for specific chemical handling and disposal guidelines.
