Indium Oxide Powder

Indium Oxide Powder

Introduction:

Indium Oxide powder is a white or yellowish powder made from indium, a rare, soft, and silvery metal. Indium oxide is produced by the oxidation of indium metal or by heating indium salts in air. This compound is widely recognized for its semiconducting properties, high transparency, and optical qualities, making it a versatile material for various advanced technological applications.

Indium oxide is part of the metal oxide family and shares some characteristics with other transparent conducting oxides (TCOs) like tin oxide and zinc oxide. Its unique properties make it valuable in electronics, displays, and solar energy technologies.

Properties of Indium Oxide Powder:

Physical Properties:

Appearance: Indium oxide is a white or yellowish-white powder.

Density: The density of indium oxide is approximately 7.24 g/cm³.

Melting Point: It has a high melting point of 1,400°C, giving it good thermal stability.

Solubility: It is insoluble in water and most solvents but soluble in strong acids.

Chemical Properties:

Electrical Conductivity: Indium oxide has semiconducting properties. It is a poor conductor in its pure form, but its conductivity can be enhanced by doping with materials such as tin oxide (SnO₂), creating materials like indium tin oxide (ITO), which is widely used in electronics.

Optical Properties: Indium oxide has a wide bandgap of about 3.5 eV, which allows it to be used in transparent conducting films and coatings.

Chemical Stability: Indium oxide is chemically stable under normal conditions, although it can react with strong acids and bases.
