1. What are Indium Oxide Granules?
Indium Oxide Granules are granular forms of high-purity indium(III) oxide (In₂O₃), an n-type semiconductor material used in thin-film deposition and advanced material processing. Their granular form provides convenient handling and controlled feeding for evaporation, PVD, and other applications requiring a stable indium oxide source.
2. What purity is available for Indium Oxide Granules?
Indium Oxide Granules are available in different purity grades, including 99.9%, 99.99%, and higher-purity grades depending on the application and impurity-control requirements. High-purity In₂O₃ is particularly important for thin-film deposition and for preparing ITO, IGZO, and other indium-based oxide materials.
3. What are Indium Oxide Granules used for?
Indium Oxide Granules are used as evaporation materials for thin-film deposition and as raw materials for indium-based oxide materials. They are commonly used in applications related to transparent conductive films, optoelectronics, semiconductor materials, displays, photovoltaic devices, and optical coatings. In₂O₃ is also an important starting material for producing ITO and other oxide sputtering targets.
4. How do I choose Indium Oxide Granules?
When choosing Indium Oxide Granules, consider the required purity, granule size, particle size distribution, morphology, density, and intended processing method. For evaporation applications, consistent granule size and low fines can help provide more controlled material feeding. For ITO or other sputtering-target production, the purity, particle characteristics, dispersion, and uniformity of the In₂O₃ raw material are important factors.
5. Can Indium Oxide Granules be customized?
Yes. Indium Oxide Granules can be customized according to required purity, granule size, particle size distribution, quantity, and packaging requirements. Custom specifications can be considered for evaporation, PVD, sputtering-target production, and other specialized material-processing applications.
6. What sizes and specifications are available for Indium Oxide Granules?
Indium Oxide Granules can be supplied in different particle or granule size ranges depending on the intended application. Specifications may include granule size, particle size distribution, purity, morphology, and packaging format. Custom sizes can also be considered when a specific evaporation source, feeding system, or downstream target-production process requires a defined material specification.
