Overview
High-purity indium sheets are thin, malleable metal sheets made from refined indium (typically 99.99% pure or higher). Indium is a rare post-transition metal valued for its unique combination of electrical conductivity, thermal properties, and plasticity. Primary production sources include zinc ore processing byproducts and recycled materials. The global market is concentrated in China, South Korea, and Canada due to refining capabilities. Demand has grown steadily with expanding electronics and renewable energy sectors.
Physical and Chemical Properties
Indium sheets exhibit exceptional ductility, allowing them to be rolled into thin foils as fine as 0.1mm without cracking. Their low melting point (156.6°C) enables low-temperature soldering applications. Chemically, indium resists corrosion in dry air but forms an oxide layer in moist environments. It reacts slowly with water and dissolves readily in acids. High-purity grades minimize impurities like lead, cadmium, and thallium, which can affect performance in sensitive applications.
Main Applications
In electronics, indium sheets serve as sputtering targets for ITO (indium tin oxide) coatings in LCD and touchscreen manufacturing. Their conductivity and transparency make them irreplaceable for these applications. The solar industry uses indium in CIGS (copper indium gallium selenide) thin-film photovoltaic cells. Other uses include cryogenic seals, thermal interface materials, and specialized solders for optoelectronics assembly.
Safety and Storage
While indium has low acute toxicity, prolonged skin contact may cause irritation, necessitating glove use during handling. Dust inhalation should be avoided with proper ventilation. Store sheets in sealed, moisture-proof containers to prevent oxidation. Avoid contact with strong acids or oxidizing agents. Shelf life is effectively indefinite if stored correctly, though surface oxidation may require cleaning before some applications.
B2B Procurement Guide
When sourcing high-purity indium sheets, prioritize suppliers with ISO certifications and batch-specific assay reports (typically ICP-MS analysis). Minimum purity for electronics applications is 99.99% (4N), with 99.999% (5N) available at premium prices. Consider logistical factors: indium's low melting point requires temperature-controlled shipping in hot climates. Standard sheet thicknesses range from 0.5mm to 5mm, with custom dimensions often requiring MOQs of 5-10kg. Spot prices fluctuate with indium market trends, so long-term contracts may offer stability.
