Indium tin oxide (ITO) powder is an inorganic functional material composed of indium oxide (In₂O₃) and tin oxide (SnO₂). It ranges in color from pale yellow to yellowish-green and is renowned for its excellent electrical conductivity, high optical transparency, good chemical stability, and ease of processing. ITO powder is widely used in transparent conductive coatings, optoelectronic devices, and advanced electronic components.
VIMATERIAL offers high-purity ITO powder in micron and nanometer sizes, with custom particle sizes available to meet application requirements. Contact us for more information.

Transparent conductive coating: Used in touch panels, displays, LCD/LED screens, and smart windows.
Solar cells: Used as transparent electrodes in photovoltaic devices to improve energy conversion efficiency.
Electronic materials: Used in conductive inks, pastes, and thin-film electronic devices.
Antistatic coating: Provides electrostatic discharge protection for precision instruments and packaging.
Optoelectronic devices: Suitable for sensors, OLEDs, and various advanced functional thin films.
Indium tin oxide powder is packaged in sealed, moisture-proof containers, typically double-layered antistatic plastic bags or aluminum foil bags, vacuum-sealed, and then placed in sturdy cartons or drums to prevent moisture, contamination, and mechanical damage during transportation.
Store in a cool, dry, well-ventilated environment, away from moisture and direct sunlight. Keep the container tightly closed to maintain product stability and performance.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
