Product Overview

Tin(IV) oxide, also known as stannic oxide, is a high-purity inorganic compound with a minimum assay of 99.9% on a trace metal basis. This fine, white powder exhibits exceptional thermal stability, making it suitable for demanding applications in material science, electronics, and chemical synthesis. Its crystalline structure ensures consistent performance in catalytic reactions, while its low electrical conductivity and high refractive index enhance its utility in optical coatings and gas sensors. The product is synthesized under stringent quality controls to minimize impurities, ensuring reproducibility in experimental and industrial processes. With a melting point exceeding 1,600°C, Tin(IV) oxide maintains structural integrity under extreme conditions, making it a preferred choice for high-temperature applications. Its chemical inertness and resistance to oxidation further extend its shelf life, reducing the need for frequent replacements. Whether used as a precursor in ceramic formulations or as a functional additive in nanotechnology, this grade of Tin(IV) oxide delivers reliability and precision, meeting the exacting standards of modern research laboratories.

FAQs

1. What is the particle size distribution of this Tin(IV) oxide powder?

The particle size typically ranges between 1-5 microns, though exact distribution may vary slightly between batches. For precise applications, we recommend verifying the certificate of analysis provided with each shipment.

2. Is this Tin(IV) oxide compatible with aqueous solutions for synthesis?

While Tin(IV) oxide is insoluble in water, it can be dispersed in acidic or alkaline solutions under controlled conditions. Pre-treatment or surface modification may be required for uniform suspension in certain solvent systems.

3. Are there lower-purity alternatives available for cost-sensitive applications?

We offer Tin(IV) oxide in 99.5% and 99.0% purity grades for applications where ultra-high purity is not critical. These alternatives provide a balance between performance and cost efficiency without compromising basic functional properties.

4. How should this product be stored to maintain its purity over time?

Store in a tightly sealed container under dry, inert conditions (e.g., nitrogen or argon atmosphere) at room temperature. Avoid exposure to moisture or reducing agents, as these can alter the oxide’s stoichiometry and surface chemistry.

5. Does this Tin(IV) oxide contain any dopants or intentional additives?

This product is supplied as undoped Tin(IV) oxide with no intentional additives. Trace impurities, if present, are quantified in the certificate of analysis and remain below the 0.1% threshold for non-metal contaminants.
