Overview
Tin oxide nanopowder (SnO₂) is a high-performance inorganic material with a wide bandgap, making it valuable in semiconductor and optoelectronic applications. Its nano-scale particle size (typically 20-100 nm) enhances surface reactivity, enabling uses in sensors, catalysis, and energy storage. As a stable n-type semiconductor, SnO₂ exhibits excellent electrical conductivity when doped. It is synthesized via methods like sol-gel, hydrothermal, or chemical vapor deposition, with properties tailored for specific industrial needs.
Physical and Chemical Properties
SnO₂ nanopowder is chemically inert under normal conditions but reacts with strong acids or reducing agents at high temperatures. Its high melting point (1630°C) and density (6.95 g/cm³) make it suitable for high-temperature applications. The material's photocatalytic activity under UV light is leveraged in environmental remediation, while its transparency to visible light and conductivity are exploited in transparent electrodes for solar cells and displays.
Main Applications
The primary use of SnO₂ nanopowder is in gas sensors (e.g., for detecting CO, NO₂, or ethanol), where its surface reactivity to gases ensures high sensitivity. It is also a key component in transparent conductive oxides (TCOs) for touchscreens and photovoltaics. In catalysis, SnO₂ serves as a support for noble metals or as a photocatalyst. Emerging applications include lithium-ion battery anodes and antimicrobial coatings, where its nano-scale properties enhance performance.
Safety and Storage
While SnO₂ is generally low-toxicity, inhalation of nanoparticles may cause respiratory irritation. Work in well-ventilated areas and use NIOSH-approved masks. Avoid skin contact to prevent dryness or irritation. Store in airtight containers away from moisture and acidic vapors. Bulk quantities should be kept in dry, temperature-controlled environments to prevent aggregation or degradation.
B2B Procurement Guide
When procuring SnO₂ nanopowder, prioritize suppliers with ISO certification and batch-specific analysis reports. Key specifications include particle size distribution (verified via TEM/DLS), purity (≥99% for most applications), and surface area (typically 30-150 m²/g). For transparent conductive films, opt for doped SnO₂ (e.g., with antimony or fluorine). Request samples to test dispersion stability in your intended solvent or matrix. Prices vary by order volume; bulk purchases (100+ kg) may reduce costs by 10-20%.
