Indium oxide is an N-type wide-bandgap transparent semiconductor material, typically appearing as a white/pale yellow powder. It possesses high transparency, conductivity, stability, and catalytic properties, and its core applications are concentrated in optoelectronic displays, semiconductors, sensors, batteries, and glass-ceramics.
Indium oxide's core applications are in optoelectronic displays and transparent conductive films. When combined with tin oxide, it forms indium tin oxide (a sputtering target used for transparent conductive coatings in LCDs, OLEDs, touchscreens, and solar cells). It is also used in energy-efficient building glass and automotive defogging/anti-icing coatings, reflecting infrared light while allowing visible light to pass through, thus improving heat insulation and anti-fogging effects. Furthermore, it is used for optical lens protection and antistatic coatings for semiconductor devices, enhancing stability and anti-interference capabilities.
It can also be used as a glass coloring and functional additive in colored and decorative glass to enhance its thermal stability and impact resistance. In the ceramics industry, it serves as a high-temperature resistant colorant and glaze additive to improve the gloss and stability of ceramics.
TOPLUS indium oxide has good electrical stability, uniform light transmission, and superior weather resistance, making it a material that cannot be completely replaced at present.
