Indium Tin Oxide Powder (ITO-26)

Description

1. Product Overview

Indium Tin Oxide Powder (ITO-26) is a high-purity, sputtering-grade ceramic target material composed of a precisely calibrated ratio of Indium(III) Oxide and Tin(IV) Oxide. It is the critical enabling material for manufacturing transparent conductive oxides (TCOs) used in flat-panel displays, touch sensors, and photovoltaic cells. The key value proposition of ITO-26 lies in its exceptional electrical conductivity (>2,000 S/cm) combined with >90% optical transmittance, directly improving device efficiency and yield. Strategically, securing a reliable ITO-26 supply chain is essential for electronics OEMs and semiconductor fabs, given indium’s critical raw material status and its irreplaceable role in next-generation displays and low-emissivity glass.

2. Key Specifications & Technical Characteristics

• Purity Level: 99.99% (4N) minimum, with 99.995% (4N5) available upon request

• Physical Characteristics:

  • Form: Fine agglomerate-free powder

  • Color: Pale yellow to greenish-yellow

  • Particle Size (D50): 0.8 – 1.5 µm (narrow distribution, suitable for slip casting)

  • Tap Density: 1.8 – 2.2 g/cm³

  • Specific Surface Area (BET): 6 – 10 m²/g

• Packaging Options: Vacuum-sealed double-layer anti-static aluminum bags (1 kg, 5 kg) or sealed HDPE drums (10 kg, 20 kg), purged with dry nitrogen.

• Shelf Life: 24 months when stored below 25°C, RH <60%, in original unopened packaging.

3. Core Industrial Applications

• Primary Industries: Consumer electronics displays, automotive touch panels, architectural smart glass, thin-film photovoltaics (CIGS and a-Si cells).

• Specific Operational Use Cases:

  • Sputtering Target Production: Pressed and sintered into planar or rotary ITO targets for DC magnetron sputtering.

  • Low-E Glass Coating: Spray-pyrolysis precursor for energy-efficient window coatings.

• Performance Advantage vs. Alternatives: Compared to fluorine-doped tin oxide (FTO) or aluminum-doped zinc oxide (AZO), ITO-26 delivers 10x lower sheet resistance at equivalent visible light transmission, enabling smaller pixel traces and faster touch response. Its uniform particle size distribution reduces target nodule formation, increasing sputtering uptime by 15–20%.

• Cost Advantage: Optimized indium oxide ratio minimizes material waste while maintaining >98% target density after sintering, lowering cost-per-wafer.

4. Competitive Advantages

• Quality Consistency: Lot-to-lot XRD phase purity (100% cubic bixbyite structure) guaranteed; each batch includes ICP-OES and GDMS certificates.

• Supply Reliability: Backward-integrated with indium refining from both primary mining and WEEE recycling, ensuring 48-week annual capacity and conflict-mineral-free documentation.

• Logistics Capability: Multi-warehouse buffer stock in Asia (3 days), Europe (5 days), and North America (7 days); real-time trackable cold-chain not required.

• Price Competitiveness: Direct ex-refinery pricing with LME indium-linked monthly index adjustments, no mid-tier distributor markup.

• Sustainability: Produced using hydrometallurgical processing with 98% water recycling; carbon footprint (scope 1 & 2) verified at 4.2 kg CO₂/kg ITO.

• Technical Support: Dedicated application engineers provide pre-sale target density modeling and post-sale sputtering parameter optimization (AVI files and in-field training included for >1 MT orders).
