1. What are Cadmium Telluride Granules?
Cadmium Telluride (CdTe Granules) are granular forms of high-purity cadmium telluride semiconductor material. CdTe is a II-VI compound semiconductor with a direct band gap of approximately 1.5 eV, widely used in thin-film photovoltaic research, semiconductor devices, and vacuum deposition applications.
2. What are Cadmium Telluride used for?
Cadmium Telluride are mainly used as evaporation materials for thin-film deposition, including physical vapor deposition (PVD), thermal evaporation, and research-scale semiconductor fabrication. They are also used in CdTe photovoltaic material development, infrared optical materials, and laboratory research.
3. What purity grades are available for Cadmium Telluride ?
Cadmium Telluride are available in high-purity grades for research and thin-film deposition applications. The suitable purity level depends on the deposition process, device requirements, and contamination control standards. Custom specifications may be available according to customer requirements.
4. What is the difference between Cadmium Telluride Powder and Cadmium Telluride Granules?
The main difference is the physical form and application method. Cadmium Telluride Powder is typically used for material synthesis, formulation, and research processes, while Cadmium Telluride Granules are commonly selected for evaporation sources and deposition processes because the larger particle size can improve handling and reduce dust generation during loading.
5. Why are Cadmium Telluride suitable for vacuum deposition?
Cadmium Telluride provide a convenient feedstock form for evaporation processes because they can be easily loaded into deposition equipment and controlled during thermal evaporation. Their granular shape helps improve material handling compared with fine powders.
6. How should Cadmium Telluride be handled and stored?
Cadmium Telluride should be handled according to appropriate chemical safety practices. Avoid generating dust during handling or processing, use suitable personal protective equipment, and store the material in a tightly closed container in a dry and well-ventilated area.
7. Are Cadmium Telluride hazardous?
Cadmium Telluride require careful handling because cadmium-containing materials are regulated hazardous substances in many regions. Avoid inhalation of dust or particles generated during processing and follow the safety instructions provided in the Safety Data Sheet (SDS).
8. Does ULPMAT provide SDS and technical support for Cadmium Telluride Granules?
Yes. ULPMAT provides technical documentation, including Safety Data Sheets (SDS), for Cadmium Telluride Granules. We support customers with material information, specifications, and application guidance for research and thin-film deposition requirements.
