Description

General description

Tin(IV) oxide, also known as stannic oxide, is a yellow-green powder that crystallizes in the rutile structure. It is a wide bandgap (3.6 eV) semiconductor with high transparency in the visible range of the electromagnetic spectrum and relatively high electronic conductivity. Its chemical stability and high purity of ≥99.99% trace metals basis make it suitable for use in demanding conditions, such as semiconductor and biomedical applications, where it is widely used in medical imaging devices, biosensors, and diagnostic tools. It is also utilized in battery technologies, including lithium-ion batteries, as a conversion-type anode material due to its high energy storage capacity and stability and a precursor for making tin compounds and complex metal oxides.
