Indium

Indium, denoted by the chemical symbol In and atomic number 49, is a soft, ductile, silvery-white metal. It is relatively rare and typically found in zinc ores and, to a lesser extent, in ores of copper and lead.

Indium doesn’t easily oxidize and can cling to glass, making it an ideal component in certain types of high-tech glass, like those used in touch screens. Additionally, its low melting point and thermal conductivity make it an attractive material in many other industrial applications.


At TXRocks, we are proud to supply a vast array of critical minerals that are indispensable to innovation across industries globally. Indium, a soft, malleable metal, is renowned for its unique properties and its use in touch screens, high-tech electronics, and more.

Critical Usecases

Flat-Panel Devices

Indium tin oxide (ITO) is used in liquid crystal displays (LCDs) and touch screens due to its excellent electrical conductivity and optical transparency.

High-Efficiency Photovoltaics

Indium gallium arsenide layers are used in high-efficiency photovoltaic solar cells.

Soldering

Indium is used in solders, where it lowers the melting point, fills gaps, and reduces soldering stress on electronic components.

Nuclear Reactors

Indium alloys are used in nuclear reactor control rods because of indium’s ability to capture neutrons.

LEDs

Certain indium compounds are used to make light-emitting diodes (LEDs) and semiconductor laser tools.
