Indium(III) oxide Usage And Synthesis
Indium oxide (also known as indium sesquioxide, or In2O3) is a yellow colored powder. It is a stable ceramic-like material that is insoluble in water. Indium oxide is an n-type semiconductor and thus can be used as a resistive element in integrated circuits. It also is used to form heterojunctions with materials like p-InP, n-GaAs, n-Si, and other semiconductors.
Other applications include glass (as a color additive), alkaline batteries (to suppress gas formation), and high current electrical switches and contacts (as an anti-arcing additive).
light green powder
Light-yellow powder; cubic crystal; occurs in both amorphous and crys-talline forms; pale-yellow amorphous form converts to crystalline form onheating at higher temperatures; isomorphous with hematite, Fe2O3; density7.18 g/cm3; melts around 2,000°C; insoluble in water; amorphous form dis-solves readily in mineral acids; crystalline form has low solubility in acids.
Indium(III) oxide is widely utilized as a n-type semiconductor, which is used in integrated circuits as a resistive element. It finds applications in batteries and as a part of some stain formulations. It is used as thin film coatings in optical, antistatic and infrared reflectors. It is doped with tin oxide and used as transparent conductive coatings.
In glass manufacture.
Indium trioxide is used in specialty glass production.
Indium trioxide may be obtained by heating indium in air or oxygen:
4In + 3O2 → 2In2O3
or by calcination of indium hydroxide, nitrate, or carbonate at elevated tem-peratures:
2In(OH)3 → In2O3 + 3H2O
In2(CO3)3 →In2O3 + 3CO2
In2O3/Au/Ag coated PET film
Wash it with H2O and dry it below 850o. It volatilises at 850o and dissolves in hot mineral acids to form salts. Store it away from light because it darkens due to the formation of free In.
