About Indium Metal

Existing amount in the earth crust is 0.05ppm and it’s generated from zinc sulfide; separate from the ashes in the zinc metallurgy, obtain the liquid of indium ion (3 of +) and make it highly pure singular matter through electrolysis. It occurs as silver white crystal. It’s soft and belongs to square crystal system. It’s stable in the air and generate In2O3 after heated up. In room temperature it can react with fluorine and chloride. It can solve in acid but not in water or alkaline solution.

What is Indium Ingot used for?

Indium Ingot (In) - Applications and Uses
 
Indium Ingot is a versatile, soft, and highly malleable post-transition metal with exceptional properties, including excellent electrical conductivity, strong adhesion to various substrates, and a low melting point. These characteristics make it a critical material in modern technology, from everyday consumer electronics to advanced energy and research systems. Our high-purity Indium Ingot serves as the foundational raw material for a wide array of cutting-edge applications.
 
Primary Applications and Industries:
 
1. Electronics & Displays (Primary Application)
The largest application for indium is in the form of Indium Tin Oxide (ITO), a transparent conductive oxide.
*   Transparent Conductive Films: Sputtered from ITO targets, indium is essential for creating the transparent conductive layers in:
    *   Flat Panel Displays: LCDs, OLEDs, and touchscreens for smartphones, tablets, televisions, and monitors.
    *   Photovoltaics: Thin-film solar cells (such as CIGS), where it serves as a transparent electrode allowing light to reach the active layer.
    *   Energy-Efficient Windows: Used in smart windows that can dynamically control heat and light transmission.
 
2. Soldering & Alloying
Indium's low melting point and ability to wet many surfaces make it invaluable in joining and coating applications.
*   Specialized Solders: Indium-based solders create reliable, low-temperature bonds in thermally sensitive components, crucial for:
    *   Electronics Assembly: Especially in step-soldering processes and for packaging sensitive devices.
    *   Thermal Management: Attaching heat sinks to delicate chips in high-performance computing.
*   Protective Coatings: Used as a thin-film coating on bearings and other moving surfaces to provide superior lubrication, reduce friction, and enhance corrosion resistance.
*   Dental Alloys: Alloyed with other metals to create strong, durable, and biocompatible dental amalgams and restorations.
 
3. Semiconductor & Advanced Research
The ultra-high-purity properties of indium are leveraged in the most advanced technological fields.
*   Compound Semiconductors: As a key Group III element, it is used in Metalorganic Vapor Phase Epitaxy (MOVPE) to grow high-performance semiconductors like Indium Phosphide (InP) and Indium Gallium Arsenide (InGaAs). These are critical for:
    *   High-Frequency Transistors
    *   Optoelectronics: Lasers and photodetectors for fiber-optic communications.
*   Research & Development: Serves as a precursor material in academic and industrial labs for developing new semiconductor devices and nanomaterials.
 
4. Nuclear Technology
*   Control Rods: Alloyed with silver and cadmium (Ag-In-Cd alloy), indium is a key component in nuclear reactor control rods, where its high neutron capture cross-section helps precisely regulate the nuclear fission reaction.

 Key Characteristics & Benefits:
 
*   High Purity: Ensures optimal performance in critical applications like semiconductor fabrication and ITO sputtering.
*   Exceptional Ductility: Can be easily rolled, extruded, and formed into various shapes, including wire and foil.
*   Superior Wettability & Adhesion: Forms strong bonds with glass, metals, and ceramics, making it ideal for soldering and coating.
*   Critical Enabler: A vital material for multiple high-growth technologies in the display, energy, and telecommunications sectors.
