Description

Indium is a soft, malleable, and lustrous post-transition metal with unique properties, including a low melting point and excellent electrical conductivity. Its primary commercial value lies in its ability to form stable, transparent conductive oxides and low-temperature fusible alloys, making it indispensable for advanced electronics and specialized soldering. This high-purity material is essential for manufacturers in the semiconductor, photovoltaics, and aerospace industries, where precision and material reliability are critical.

Application

• Transparent Conductive Oxides (TCOs): A key component in indium tin oxide (ITO) coatings for liquid crystal displays (LCDs), touch screens, and photovoltaic cells.
• Semiconductor Manufacturing: Used in compound semiconductors like indium phosphide (InP) and indium gallium arsenide (InGaAs) for high-frequency and optoelectronic devices.
• Low-Temperature Solders & Alloys: Forms fusible alloys for thermal interface materials, soldering in temperature-sensitive electronics, and as a sealant in glass and ceramics.
• Photovoltaics: Employed in copper indium gallium selenide (CIGS) thin-film solar cells.
• Thermal Interface Materials: Used in indium-based thermal pastes and pads for efficient heat dissipation in high-performance computing.
• Aerospace & Defense: Utilized in specialized bearings, coatings, and infrared detection systems.
• Nuclear Reactor Control: Serves as a neutron absorber in control rods due to its high neutron capture cross-section.

Quality Control

Our indium is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity, typically ranging from 99.99% (4N) to 99.9999% (6N) for electronic-grade applications. Quality is verified through advanced analytical techniques including Glow Discharge Mass Spectrometry (GDMS) and Inductively Coupled Plasma (ICP) analysis. A comprehensive Certificate of Analysis (COA) detailing purity and trace metal content is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). For long-term storage of high-purity grades, consider sealing under an inert atmosphere such as argon to minimize surface oxidation. Keep away from strong acids and strong oxidizing agents.
