Description

Gallium CAS NO 7440-55-3 is a soft, silvery-white post-transition metal with a low melting point just above room temperature. This unique physical property makes it an indispensable material in advanced electronics and semiconductor manufacturing. It is a critical raw material for industries requiring high-purity metals for compound semiconductors, specialty alloys, and advanced cooling systems.

Application

• Semiconductor Manufacturing: Primary use in the production of gallium arsenide (GaAs) and gallium nitride (GaN) wafers for high-frequency, high-power, and optoelectronic devices (LEDs, laser diodes, solar cells).
• Alloy Production: Used to create low-melting-point alloys (e.g., Galinstan) for applications in thermal management, fire sprinklers, and flexible electronics.
• Medical & Dental: Component in some radioisotopes (like Gallium-67) used for medical imaging and diagnostics, and in certain dental alloys.
• Research & Development: Employed in experimental physics (e.g., neutrino detection) and as a liquid metal coolant in advanced nuclear reactors and high-performance computing.
• Mirrors & Optics: Used to create highly reflective gallium-based coatings for astronomical and specialized optical instruments.
• Catalysts: Serves as a catalyst or catalyst promoter in certain organic synthesis and petroleum refining processes.

Quality Control

Our gallium is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity levels suitable for demanding industrial and electronic applications. We provide comprehensive Certificates of Analysis (COA) detailing purity, trace metal analysis, and other critical parameters. Quality assurance aligns with relevant industry standards for high-purity metals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and strong oxidizers. Due to its low melting point, storage temperature should be considered based on the physical form (solid or liquid) required. For long-term storage of high-purity grades, an inert atmosphere may be recommended to prevent surface oxidation.
