Description

Hydrogen Telluride is a highly toxic, flammable, and malodorous inorganic gas. It serves as a critical precursor in the synthesis of metal tellurides and organotellurium compounds, which are essential for advanced material science. This compound is primarily utilized by researchers and manufacturers in the semiconductor, nanotechnology, and specialty chemical industries for applications requiring precise tellurium doping or thin-film deposition.

Application

• Semiconductor Manufacturing: As a key precursor for Metal-Organic Chemical Vapor Deposition (MOCVD) to produce cadmium telluride (CdTe) and mercury cadmium telluride (MCT) thin films for infrared detectors and photovoltaic cells.
• Nanomaterial Synthesis: Used in the preparation of tellurium-based nanowires, quantum dots, and two-dimensional materials with unique electronic and optical properties.
• Organometallic Chemistry: Acts as a fundamental reagent for introducing tellurium into organic molecules, creating novel catalysts and ligands.
• Doping Agent: Employed in the precise doping of semiconductor crystals to modify their electrical characteristics.
• Research & Development: Essential for academic and industrial R&D exploring the chemistry and applications of tellurium compounds.
• Specialty Gas Mixtures: Used in calibrated gas mixtures for analytical instrument calibration and process control in high-tech manufacturing.

Quality Control

Our Hydrogen Telluride is produced and handled under stringent conditions to ensure the highest purity and consistency for sensitive applications. We provide comprehensive quality assurance, with product specifications tailored to meet the rigorous demands of semiconductor fabrication and advanced material synthesis. A detailed Certificate of Analysis (COA) is supplied with each shipment, verifying purity, identity, and impurity profiles through advanced analytical techniques.

Storage

Preserve in a tightly closed, specially passivated container, protected from light. Store in a cool, well-ventilated area, away from heat, ignition sources, and incompatible materials such as strong oxidizers. Due to its gaseous, toxic, and pyrophoric nature, it must be stored under an inert atmosphere (e.g., nitrogen or argon) in a certified gas cylinder with appropriate pressure regulation. Storage temperature should be maintained at or below room temperature (15-25°C) as specified.
