What is a Indium oxide (In₂O₃)?

Indium oxide (In₂O₃) is an inorganic compound composed of indium and oxygen, typically found as a white or yellow powder. Indium is a metal element used primarily in semiconductors and optical devices, and indium oxide is one of its oxide forms. It possesses excellent electrical conductivity and transparency, making it a key material in various industries. One of its main uses is as a transparent conductive oxide (TCO), particularly in applications such as thin-film displays, touch panels, and solar panels. Its ability to conduct electricity while remaining transparent is crucial in these devices.

Indium oxide is also utilized as a chemical catalyst and in sensor applications. It plays an important role as a catalyst in chemical reactions and as a sensor material for gases such as oxygen and hydrogen. Additionally, indium oxide is used in optical devices like LEDs and lasers. Indium-containing compounds are vital in efficient light-emitting elements, contributing to advancements in optical communications and display technologies. With its exceptional properties, indium oxide is expected to continue playing a vital role in advanced technologies.
