What is Tin Oxide?
Tin Oxide (CAS 18282-10-5), also known as Stannic oxide, is an inorganic compound used industrially as a catalyst, conductive coating material, and functional ceramic additive.
Where is Tin Oxide used?
- Electronics: transparent conductive coatings on glass and display substrates for touch screens, solar panels and low-emissivity window films
- Catalysis: catalyst or catalyst precursor for oxidation reactions in gas sensing and exhaust treatment
- Cleaning formulations: mild abrasive and polishing agent in metal and glass finishing compounds
- Ceramics and glass: opacity, surface hardness and refractive properties in glazes and specialty optical glass
- It supports environmental monitoring and emission control.
Commercial specifications
- Fine white powder in varying particle size distributions
- Technical and high-purity grades
- Electronic and catalyst grades
- Packaging from kilogram-scale bags to bulk quantities
