Description

Antimony Tin Oxide (ATO) Nanopowder is a high-purity, conductive ceramic material composed of antimony-doped tin oxide nanoparticles. This advanced functional material is valued for its exceptional combination of high electrical conductivity and optical transparency, making it a critical component in modern electronic and optical applications. It is essential for manufacturers and R&D teams in the electronics, coatings, and energy sectors seeking to develop transparent conductive films, static-dissipative composites, and smart window technologies.

Application

• Transparent Conductive Films (TCFs): Used as a cost-effective alternative to indium tin oxide (ITO) in touch screens, LCDs, OLEDs, and solar cells.
• Antistatic & EMI Shielding Coatings: Formulated into paints, plastics, and textiles to provide static dissipation and electromagnetic interference protection.
• Energy-Efficient Glazing: A key component in Low-E (low-emissivity) glass and smart windows for thermal insulation and infrared reflection.
• Gas Sensors: Serves as a sensitive material in semiconductor-type sensors for detecting combustible and toxic gases.
• Catalyst & Catalyst Support: Employed in oxidation reactions and as a support for precious metal catalysts.
• Lithium-Ion Battery Anodes: Investigated as a high-capacity anode material to improve battery performance and cycle life.

Quality Control

Our Antimony Tin Oxide Nanopowder 99.5+% is produced under stringent quality management protocols. Each batch undergoes comprehensive analysis to verify critical parameters including purity, particle size distribution (D50), specific surface area (BET), and antimony doping concentration. A Certificate of Analysis (COA) detailing these results is provided with every shipment to ensure traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, this material must be stored in a cool, dry place, ideally under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and oxidation. Recommended storage temperature is 15-25°C. The container should be kept sealed when not in use.
