Gallium telluride Granules is a III-VI compound semiconductor material composed of gallium and tellurium, with the chemical formula Ga₂Te₃. The product typically appears as metallic-luster gray-black particles or bulk material. It possesses a narrow bandgap (approximately 0.7–1.7 eV) and exhibits unique thermoelectric properties, infrared optical characteristics, and phase-change behavior. It serves as a key raw material for fabricating mid-to-far infrared detectors, high-efficiency thermoelectric converters, and novel phase-change storage materials.
We offer high-purity Ga2Te3 Granules in multiple purity grades and particle size specifications, with professional custom packaging available. Contact us for samples.

Q1: How should Ga2Te3 Granules be stored?
A1: Store in sealed, dry, light-protected containers. Keep in an inert atmosphere or vacuum environment, strictly isolated from air and moisture to prevent oxidation.
Q2: Is it safe to use?
A2: Tellurium compounds are toxic and require protective measures. Wear protective equipment during handling, work in a well-ventilated area, and avoid inhalation or skin contact.
Q3: How should purity be selected?
A3: Depends on the end application. For fundamental research, 4N grade (99.99%) is sufficient; for fabricating high-performance devices, 5N (99.999%) or higher purity is recommended.
Q4: What are its key advantages?
A4: Narrow bandgap and high thermoelectric figure of merit. It effectively responds to infrared light and efficiently converts thermal energy into electricity, delivering outstanding performance in specific applications.
