Description

Tin (Iv) Oxide CAS NO 18232-10-5 is a high-purity inorganic compound, also known as stannic oxide, prized for its exceptional chemical stability and electrical properties. This material is critical for industries requiring precise, reliable, and high-performance ceramic or conductive components. It serves as a fundamental raw material for manufacturers in the electronics, ceramics, glass, and catalyst sectors, where consistent quality is paramount for end-product performance.

Application

• Electronic Ceramics & Varistors: A key component in the formulation of dielectric and semiconducting ceramics for multilayer capacitors, varistors, and sensors.
• Optical Glass & Polishing: Used as an opacifier and polishing agent for glass, stone, and metals, providing a fine, scratch-free finish.
• Catalyst & Catalyst Support: Employed as a catalyst or catalyst support in oxidation-reduction reactions and organic synthesis processes.
• Conductive Coatings & ATO: Serves as a precursor for Antimony-doped Tin Oxide (ATO), a transparent conductive oxide used in coatings and displays.
• Ceramic Glazes & Pigments: Acts as an opacifier and color stabilizer in ceramic glazes and inorganic pigments.
• Gas Sensors: Utilized in the sensitive layer of semiconductor gas sensors for detecting combustible or toxic gases.
