1. What is Indium Oxide Powder?
Indium Oxide Powder (In₂O₃) is a high-purity inorganic oxide material with semiconductor properties and a ceramic-like structure. It is widely used as a raw material for transparent conductive oxide materials, sputtering target manufacturing, semiconductor research, optoelectronic applications, and other advanced material technologies.
2. What is Indium Oxide Powder used for?
Indium Oxide Powder is mainly used for manufacturing ITO (Indium Tin Oxide) sputtering targets, indium-based oxide materials, semiconductor materials, transparent conductive films, and advanced electronic components. It is also used in optical coatings, sensors, ceramics, and other specialized applications where high-purity In₂O₃ is required.
3. What is the difference between Indium Oxide Powder and ITO Powder?
Indium Oxide Powder (In₂O₃) is pure indium oxide, while ITO Powder is a doped material consisting mainly of In₂O₃ combined with tin oxide (SnO₂). ITO is commonly used for transparent conductive films because tin doping improves electrical conductivity, while pure In₂O₃ is selected when an undoped indium oxide composition is required.
4. What purity is available for Indium Oxide Powder?
Indium Oxide Powder is available in high-purity grades such as 99.99% (4N) depending on application requirements. Higher-purity In₂O₃ is typically selected for semiconductor, thin-film, sputtering target, and advanced electronic material applications where impurity control is important.
5. How do I choose Indium Oxide Powder?
When choosing Indium Oxide Powder, consider purity, particle size distribution, morphology, surface area, density, and the intended application. For sputtering target production, powder characteristics such as particle uniformity, dispersion, and sintering behavior can influence target density and thin-film deposition performance.
6. What particle sizes and specifications are available for Indium Oxide Powder?
Indium Oxide Powder can be supplied in different particle size ranges and specifications depending on the application. Available specifications may include micron-size powder, fine powder, target-grade powder, particle size distribution, morphology, and packaging options. Custom specifications can be provided according to downstream processing requirements.
7. Can Indium Oxide Powder be customized?
Yes. Indium Oxide Powder can be customized according to required purity, particle size, morphology, surface characteristics, quantity, and packaging requirements. Customized In₂O₃ powder solutions can be supplied for applications including sputtering target production, electronic materials, semiconductor research, and advanced oxide material development.
