Cell Lab 5N (99.999%) Selenium (Se) Pieces Evaporation Materials [1–3 mm]

High-Purity Selenium for Thin Film and Photoconductor Applications

General Description

Cell Lab 5N (99.999%) Selenium (Se) Pieces are high-purity evaporation materials featuring a grey metallic lustre and excellent reactivity balance. Selenium is primarily used in thin-film deposition, X-ray photoconductors, quantum dots, and antibacterial coatings.
Its superior purity and fine particle size make it suitable for optical coatings, photovoltaics, and semiconductor device fabrication, ensuring reliable performance in precision vacuum evaporation systems.

This material’s relatively high vapour pressure at low temperatures requires careful handling to prevent cross-contamination in deposition chambers. It is classified as a hazardous material and must be shipped with proper packaging and documentation.

FAQ

Q1: What is the advantage of using 5N-grade selenium in coating applications?
Its ultra-high purity reduces contamination during vacuum deposition, improving thin-film uniformity and conductivity.

Q2: Can selenium be co-evaporated with other materials?
Yes. Selenium is often co-evaporated with elements such as cadmium, zinc, or tellurium to form compound semiconductors like CdSe or ZnSe.

Q3: What precautions are needed when handling selenium?
Selenium has a high vapour pressure at low temperatures; handle it in a controlled vacuum or inert atmosphere to prevent contamination and oxidation.

Q4: Is special packaging required for shipping?
Yes. Selenium is classified as a hazardous material and must be shipped with proper hazmat packaging and handling procedures.
