Tin(IV) oxide

Tin(IV) oxide (CAS 18282-10-5, EC 242-159-0) is an inorganic compound of tin and oxygen, also referred to as stannic oxide or tin dioxide, with the molecular formula O2Sn. It carries no assigned E-code and is classified under Salts & Minerals. It is commercially available in nanopowder form.

In electronics manufacturing, tin(IV) oxide serves as a semiconductor material in gas sensors, where its surface conductivity changes measurably in response to reducing gases such as carbon monoxide. In industrial cleaning formulations, it functions as a catalytic oxidation agent, accelerating the breakdown of organic soil compounds under controlled conditions.

Tin(IV) oxide is supplied as a nanopowder grade and is subject to REACH registration requirements within the European Union. Procurement should confirm particle size specifications and SDS documentation prior to ordering. Standard packaging formats vary by supplier; buyers should request COA and compliance documentation at point of enquiry.
