Description
Overview
Indium, a soft and silvery-white metal, is primarily obtained as a byproduct during the refining of zinc ores, undergoing meticulous purification to meet the high standards required for advanced technological applications. Valued for its low melting point of 156.6°C and excellent electrical conductivity, indium is a critical material in the production of indium tin oxide (ITO), a transparent conductive coating essential for flat-panel displays, touchscreens, and solar cells. Its malleability and ability to form thin films also make it ideal for use in semiconductors, low-temperature solders, and thermal interface materials in electronics. Indium’s scarcity and recyclability underscore its importance as a sustainable resource in the rapidly evolving high-tech and renewable energy sectors.
